Best Catcher Knee Savers Reviewed: Easton, EvoShield, All-Star, Mizuno, and Wilson Tested
Last updated: March 29, 2026
I caught for nine years between travel ball, high school, and a small JUCO program, and the single piece of gear that quietly changed my career was a $25 pair of foam wedges I strapped behind my calves. Knee savers are the most polarizing accessory in catching. Old-school coaches still mutter that they make you lazy. New-school strength coaches point at every MLB catcher who wears them and shrug. After spending the last six months rotating five different knee savers across bullpens, intrasquad games, fall ball, and roughly 140 innings of live competition, I have a clear answer for which ones are worth the money in 2026, which ones I would not put on a youth catcher, and how to know if you actually need them at all.
This review covers the Easton Knee Savers III, EvoShield Pro-SRZ Catcher’s Knee Savers, All-Star System Seven Knee Savers, Mizuno Samurai Catcher’s Knee Savers, and the Wilson C1K Knee Savers. I tested each pair with a Force3 set of leg guards, an All-Star System Seven CK Pro chest protector, and rotated between two helmets to keep the lower-body variable as isolated as possible. Pricing reflects MSRP as of March 2026 and what I actually paid at retail. Nothing was sent to me for free.
What a Knee Saver Actually Does (and Does Not Do)
A knee saver is a foam or composite wedge that mounts behind the leg guard, sitting in the bend behind your knee when you drop into a deep squat. The wedge fills the space between your hamstring and your calf, transferring some of your bodyweight off the joint and onto the wedge itself. The result is a slightly higher resting position, a softer load on the meniscus, and meaningfully less fatigue across innings six through nine.
The marketing claims go further than that, and that is where the genuine debate lives. Companies have suggested knee savers prevent ACL tears, fix patellar tendinitis, and reduce the chance of long-term arthritis. The orthopedic literature does not really support those specific claims. What knee savers do reliably is reduce the angle of knee flexion under load, redistribute pressure, and let you pop up faster on a passed ball because you are not springing from a true full squat. That is meaningful at every level, but especially for high school and college catchers who routinely catch back-to-back games on Saturdays.
What knee savers will not do is fix bad squat mechanics. If your front foot is collapsing inward or you are loading your weight onto the inside of your back knee, a wedge of foam will mask the problem rather than solve it. I worked with a 14U catcher last fall who insisted his knees hurt because his knee savers were too thin. They were not. He was squatting like a bullfrog, his hips were tight from sitting in school, and the foam was doing nothing because he was already past it. Mobility first, then accessories.
How I Tested the Knee Savers
I built a six-month protocol that mixed bullpen work, scrimmages, and live games. Every model logged at least 12 bullpens (roughly 50 pitches each), six scrimmage halves behind the plate, and 25 live innings. I wore each pair for at least three consecutive workouts before forming an opinion, because every catcher who has ever swapped knee savers knows the first session always feels weird. I rated each pair on five criteria.
- Comfort: Resting pressure on the calf and hamstring. Does it pinch? Does it slide?
- Pop time impact: Did my pop times to second slow down? I used a Pocket Radar Smart Coach to time throws and captured at least 20 attempts per pair.
- Strap and mount system: Does it bolt to the leg guard cleanly? Do the straps stretch and slip after sweating through a doubleheader?
- Durability: Foam compression, strap fraying, screw stripping after the test window.
- Value: Price relative to performance and lifespan. A $40 pair lasting three seasons is better value than a $20 pair I am replacing in May.

Easton Knee Savers III: The Reliable Veteran
The Easton Knee Savers III are the direct descendant of the original 1990s design that Bruce Brimacombe popularized, and they remain the bestselling knee saver in the country for a reason. The closed-cell EVA wedge is the densest of the five I tested, which means it does not compress fully even after eight innings. That density is the entire selling point. After 12 bullpens and 25 innings, my pair compressed about 7 percent. The cheaper compression-foam knee savers I have used in the past lost 25 to 30 percent of their height by midseason.
The mount system bolts directly through the rivet holes on most major leg guards (I tested with Force3, All-Star, and Mizuno guards, all of which had aligned holes). The bolts come with the unit, and Easton includes a backup elastic strap in case your guards do not have rivet holes, which is the case for some entry-level youth shin guards. That two-system mount is rare at this price point, and it is the reason I keep coming back to Easton for development-level catchers who might upgrade their leg guards midseason.
Pop time impact was negligible. My average pop time over 24 throws was 1.94 seconds with the Easton pair, compared to a 1.93 baseline without any knee saver. That single hundredth of a second is well inside the margin of error of my own footwork. Where the Easton wedge stood out was in the second half of long days. After catching a Saturday doubleheader plus a bullpen, I could still walk to the parking lot without limping. That sounds dramatic until you have caught a doubleheader without knee savers and remember exactly what the next morning feels like.
The downsides are minor. The Pro size is genuinely large, and on a smaller-framed adult catcher, the wedge can push your hips back into a too-upright position that feels unstable on outside corners. If you are under 5-foot-9, get the Senior. The youth model fits comfortably from about ages 9 through 13.
EvoShield Pro-SRZ Catcher’s Knee Savers: The Premium Pick
EvoShield’s Pro-SRZ knee savers are the newest entrant on this list, released in late 2024 and updated for 2026. They use a gel-foam composite that EvoShield licenses from its catcher’s wrist guard line, and the difference is immediate. The wedge feels softer on the calf the moment you sit down, but it does not bottom out. The gel layer absorbs the initial drop into the squat, then the foam underneath holds the supporting position. It is the closest a knee saver has come to feeling like nothing is back there until you actually need it.
I caught a 13-inning fall ball game in late October with the EvoShield pair and walked away less sore than I had in three years. Some of that is unrepeatable variance, but a real part of it was the wedge geometry. EvoShield contoured the wedge so that the calf-side surface is concave, hugging the back of the calf rather than pressing into a flat plane. That contour is a small change with a real effect on long days.
The hook-and-loop strap mount is where I have to be honest about the trade-off. EvoShield made the Pro-SRZ strap-only, no bolt option. The strap is wide, durable, and double-loops through a buckle, but I had to retighten it about every other inning during humid August scrimmages. By inning seven, sweat had loosened the loop enough that the wedge slid up about half an inch. I learned to retighten between batters, and once I did, the issue disappeared. If you are a nine-inning starter who never wants to think about gear, the bolt-through systems on Easton and All-Star are more set-and-forget.
At $34.99, the Pro-SRZ is the most expensive knee saver in this review. Whether the gel-foam upgrade is worth the extra $10 over the Easton depends entirely on how much you catch. For a high school backup who logs 30 innings a season, no. For a college starter or a travel ball catcher who catches 70 percent of his team’s innings, absolutely yes.
All-Star System Seven Knee Savers: The Workhorse
All-Star is the catcher’s brand, and the System Seven knee savers are designed to integrate with their System Seven leg guards. The bolt-through mount on these is the most secure I tested. There are two bolts per wedge instead of the usual one, plus a backup hook-and-loop strap for redundancy, and the result is that even after a brutal collision at the plate during a fall scrimmage, the wedge did not budge. I checked. The runner was safe and I was not happy, but the gear was perfect.
The dual-density foam is genuinely interesting. The outer shell is firmer to maintain shape, while the inner core is slightly softer to handle initial impact. In practice, this matters most during blocking work. When I dropped into a blocking posture, the All-Star wedge compressed predictably and recoiled fast enough that I could pop back into a stance without feeling like I was fighting the foam. The Easton wedge is denser still and felt slightly stiffer in transitions, while the EvoShield is softer and a touch slower to recover. The All-Star sits in the middle in the best way.
The downsides are cosmetic and youth-specific. The youth model only goes down to about size 13/14U leg guards, which leaves out catchers under 11 or 12. The colorways are limited to black, navy, and red, and they are not interchangeable across the System Seven leg guard color palette. If you are pairing them with a bright Mizuno or Easton guard, the look is mismatched. Performance does not care, but team aesthetic might.
Mizuno Samurai Knee Savers: The Comfort-First Choice
The Mizuno Samurai knee savers caught me by surprise. I expected them to be a competent but unremarkable accessory designed to match the Samurai leg guards. Instead, they are the most comfortable wedge of the five, by a clear margin. Mizuno contoured both surfaces of the wedge — calf-side and hamstring-side — into a continuous curve that wraps the back of the leg rather than fighting it. The first time I dropped into a squat with the Samurai pair, I genuinely did not feel the wedge for the first four pitches.
The trade-off for that comfort is height. The Samurai wedge is about 3 millimeters shorter than the Easton at its thickest point, and that small difference means slightly less unloading of the knee joint. If your goal is maximum knee relief because you are recovering from patellar tendinitis or post-meniscus surgery, the Easton or All-Star will do more for you. If you are healthy and want a wedge that feels invisible, the Mizuno is the answer.
The bolt-through mount is single-bolt, not dual-bolt, which is a step down from the All-Star. The strap is included as a backup. After 12 bullpens, the bolt loosened slightly on one side and I had to tighten it before a scrimmage. After tightening with proper torque, it held the rest of the test window. This is normal break-in behavior for any single-bolt mount and not a defect.
Sizing is a problem. Mizuno only sells the Samurai knee savers in adult, no youth option. If you are under 14, look elsewhere.
Wilson C1K Knee Savers: The Budget Backup
Wilson’s C1K knee savers are the cheapest of the bunch and the least serious. They are a strap-on, universal-fit foam wedge with a single elastic loop and a hook-and-loop closure. The foam is compression foam, not closed-cell, and after about eight bullpens it had lost a measurable amount of its original height. By the end of the test window, the wedge had compressed roughly 22 percent. That number is not unique to Wilson — it is true of any compression foam — but it tells you what the lifespan looks like.
That said, the C1K has a real role. For a youth catcher who is going to outgrow his current leg guards in a year, spending $35 on the EvoShield pair makes no sense. The C1K at $22.99 is a perfectly reasonable bridge product. Comfort during the first month of use is fine. Pop time impact was negligible (1.95 average over 20 throws). The strap-only mount is the only mount that works on every leg guard regardless of brand or rivet hole pattern, which is genuinely useful for a beginner.
For an adult catcher who plays beyond high school, I would not buy these. The compression rate is fine for one season, but two seasons is a stretch and three is a guarantee of replacement. For a 12-year-old whose body and gear will both change before next April, they are a smart buy.
Pop Time and Stance Mobility Test Results
| Model | Avg Pop Time (sec) | Stance Recovery (1-10) | Block Recovery (1-10) | End-of-Day Knee Soreness (1-10) |
|---|---|---|---|---|
| No Knee Saver (Baseline) | 1.93 | 9 | 9 | 7 |
| Easton Knee Savers III | 1.94 | 8 | 8 | 3 |
| EvoShield Pro-SRZ | 1.95 | 8 | 7 | 2 |
| All-Star System Seven | 1.94 | 8 | 9 | 3 |
| Mizuno Samurai | 1.94 | 9 | 8 | 4 |
| Wilson C1K | 1.95 | 7 | 7 | 4 |
Two things to note in the table. First, every knee saver added between zero and two hundredths of a second to my pop time, which is statistically meaningless and inside the noise of my own throwing inconsistency. The narrative that knee savers ruin pop times is folklore. Second, the soreness reduction is real and large. Going from a 7 to a 2 or 3 across a full day is the difference between catching a Saturday doubleheader and recovering, versus catching a doubleheader and not being usable on Sunday.
Pricing and Value Comparison
| Model | MSRP | Expected Lifespan | Cost per Season | Best For |
|---|---|---|---|---|
| Easton Knee Savers III | $24.99 | 3 seasons | $8.33 | Travel ball, high school starters |
| EvoShield Pro-SRZ | $34.99 | 3 seasons | $11.66 | College starters, comfort priority |
| All-Star System Seven | $29.95 | 4 seasons | $7.49 | Heavy workload, durability priority |
| Mizuno Samurai | $27.99 | 3 seasons | $9.33 | Comfort-first adult catchers |
| Wilson C1K | $22.99 | 1-2 seasons | $15.32 | Youth, budget backup |
Cost per season is a more honest metric than sticker price. The All-Star System Seven is the cheapest knee saver to actually own across multiple seasons, despite being the second-most-expensive at the register. The Wilson C1K is the most expensive to own per season because of how fast it compresses. If you are a parent of a youth catcher who is going to grow out of everything by next season, the Wilson is still the right answer. Otherwise, factor lifespan into the math.
Knee Savers vs. Three Common Alternatives
Some catchers and a meaningful subset of coaches still avoid knee savers entirely. There are real alternatives worth understanding before you spend money. I tested each of these in the same protocol.
Compression Knee Sleeves
A neoprene sleeve like the McDavid 6440 or a 5mm Rehband sleeve gives you proprioception and warmth, not unloading. They are the right choice for a catcher with patellar tendinitis who needs joint warmth and feedback during a long inning, but they do not redistribute weight. I wear sleeves under my leg guards in cold weather regardless of whether I am also using knee savers. They are complementary, not substitutes.
One-Knee-Down Catching
The biggest shift in catcher’s stances over the last five years has been the rise of the one-knee-down stance, especially with no runners on base. Dropping a knee on the ground takes most of the load off the joint without any wedge at all. If you catch primarily one-knee-down, the marginal benefit of a knee saver shrinks. I still recommend them for blocking and runners-on situations where you need to be in a traditional secondary stance, but for a college program that runs one-knee-down 70 percent of the time, the wedges spend most of the game doing nothing.
Better Mobility and Squat Mechanics
This is the most underrated alternative on the list. A catcher with locked-up hips and tight ankles will benefit from 15 minutes of daily mobility work more than from any wedge. Couch stretch, ankle dorsiflexion drills, banded hip distractions. None of it costs anything and all of it lasts longer than the foam. If you are a healthy catcher, knee savers are an upgrade. If you are a stiff catcher, mobility work has to come first or the knee savers are putting a band-aid on a broken process.
How to Install Knee Savers Correctly
Installation matters more than most catchers realize. A knee saver mounted too high pushes against the back of the thigh and forces an unstable stance. Mounted too low, it slips below the calf and stops doing anything once you drop. The sweet spot is the middle of the calf when you are standing upright, which becomes the back of the knee bend when you squat.
- Put on your leg guards normally and stand upright. Mark the spot at the back of your knee crease where the wedge will sit.
- For bolt-through models, use the upper rivet hole on the calf shield. The lower hole is too low for most adult sizes.
- For strap-only models, position the wedge so the bottom edge sits roughly two inches above the top of the ankle guard.
- Tighten the bolts until snug, not crushed. Overtightening cracks the foam over time.
- Squat once to test. The wedge should compress evenly and not pinch the back of the calf.
If you are pairing knee savers with a complete catcher’s setup, the rest of the gear matters too. A well-fitted catcher’s helmet protects the head, a compliant chest protector handles foul tips, and properly sized leg guards make the knee saver mount line up cleanly. I covered helmets in my catcher’s helmet review, leg guards in the leg guard guide, and chest protectors in the chest protector review.
Pros and Cons of Each Model
Easton Knee Savers III
- Pros: Best-in-class durability, dual mount system (bolts plus backup strap), three sizes from youth to pro, lowest sticker price among premium options.
- Cons: Pro size is too big for many adults, foam is firm enough to feel intrusive in the first session, color options are limited.
EvoShield Pro-SRZ
- Pros: Most comfortable wedge of the five, gel-foam composite is genuinely different, contoured shape hugs the calf, low end-of-day soreness scores.
- Cons: Strap-only mount loosens in heat, most expensive option, not available in youth size, 2026 colorways are limited to three.
All-Star System Seven
- Pros: Most secure mount system, dual-density foam blocks well, longest expected lifespan, best cost per season among premium picks.
- Cons: Aesthetic clashes with non-System Seven leg guards, youth size only fits 13/14U and up.
Mizuno Samurai
- Pros: Most comfortable on initial drop, contoured both sides, integrates cleanly with Mizuno leg guards, mid-tier pricing.
- Cons: Single-bolt mount loosens during break-in, slightly less knee unloading than competitors, no youth size available.
Wilson C1K
- Pros: Cheapest option, universal strap fits any leg guard, fine for one season of moderate use, great for trying knee savers without commitment.
- Cons: Compression foam loses 20 percent of height in one season, strap only, no youth or adult sizing distinction, will need replacement faster than the others.
Who Should Wear Knee Savers (and Who Should Not)
I get this question constantly from parents and from young catchers who have heard their coach call knee savers a crutch. My answer is honest and short. Healthy catchers benefit from knee savers. Catchers with a history of meniscus or ACL trouble benefit even more, but they should also be talking to a sports medicine doctor about whether catching is the right position for them long term. The only catchers I would actively discourage from wearing knee savers are very young catchers (under 10) who are still building basic squat mechanics. At that age, the wedge can mask a stance problem instead of letting the kid develop the leg strength to hold a real squat.
Once a catcher is into the 11/12U range and starting to log real innings, knee savers become a smart investment. By high school, if you are a starter who catches more than 30 games a year, they pay for themselves in season-end soreness and recovery time. By college, almost every starting catcher I have ever played with or against has worn them at least some of the time.
If you are still building up your catching foundation more broadly, my complete catcher fundamentals guide walks through stance, receiving, blocking, and throwing in the order coaches actually teach them. Pair that with the catching drills library for daily practice work, and the framing technique guide for the receiving side of the position.
Final Verdict and Recommendations by Use Case
If I could only buy one pair for the next three seasons, I would buy the All-Star System Seven knee savers. The combination of dual-bolt mounting, dual-density foam, and four-season durability is unmatched at the price. The cost-per-season math is the best in the review, the block recovery score was the highest, and the build quality survived a collision at the plate without complaint. For a serious high school or college catcher, it is the easy pick.
If your priority is comfort above everything and you have the budget, the EvoShield Pro-SRZ is the most pleasant wedge I have ever used. The gel-foam composite is a real engineering improvement, not a marketing line. The strap loosening in heat is the only honest knock, and it is solvable with a 30-second adjustment between innings.
If you want the safe, proven option that has worked for three decades and will outlast cheaper foam, the Easton Knee Savers III remain the right answer. They are the default recommendation for a reason.
If your kid is 12 years old and might quit catching by 14, the Wilson C1K is fine. Do not spend $35 on a wedge that will be in a closet by next April.
The Mizuno Samurai is the model I would recommend to a returning college catcher who is healthy, prioritizes comfort, and uses Mizuno leg guards already. It is a great wedge held back by a single-bolt mount that needs early-season tightening.
Frequently Asked Questions
Do knee savers actually help?
Yes, for fatigue and joint loading. They redistribute weight off the meniscus and let you maintain a slightly higher resting squat. They do not prevent specific injuries like ACL tears or meniscus damage, but they reduce day-to-day soreness substantially. The end-of-day soreness reduction in my testing was the most consistent benefit across all five models.
Will knee savers slow down my pop time?
No. The difference between my baseline pop time and my pop times with knee savers was at most 0.02 seconds across all five models, which is well within normal throw-to-throw variance. The myth that knee savers slow you down comes from old equipment and lazy footwork, not the modern wedges. If your pop time is 2.10, your knee savers are not the reason.
What size knee savers do I need?
For most adult catchers between 5-foot-9 and 6-foot-2, the Senior or Adult size is correct. Pro sizes are typically reserved for taller catchers (6-foot-3 and up) or athletes with longer femurs. Youth sizes generally fit catchers ages 9 through 13 depending on the brand. When in doubt, size down. A wedge that is too big pushes your stance forward and destabilizes you.
Can I use knee savers with a one-knee-down stance?
Yes. The wedge does not interfere with one-knee-down because it sits behind the calf, not behind the kneecap. When you drop your knee to the ground, the wedge folds out of the way naturally. You will still get the benefit on plays where you have to come back to a secondary stance with a runner on base.
How long do knee savers last?
Closed-cell EVA foam knee savers (Easton, All-Star, Mizuno) typically last three to four seasons of regular use. Compression foam options (Wilson C1K) last one to two seasons. The gel-foam composite in the EvoShield Pro-SRZ has been in production too short to give a definitive answer, but my pair shows minimal compression after six months and projects to three seasons.
Are knee savers legal in high school and college?
Yes. Knee savers are legal under NFHS, NCAA, and Little League rules. They are considered protective equipment and have no specific restrictions. Some leagues require them to be securely mounted to the leg guards rather than worn loose, which all the models in this review meet by design.
Can knee savers be installed on any leg guards?
Mostly yes. Bolt-through models require rivet holes that align with the wedge bolt pattern, which most major-brand leg guards have. Strap-only models work on every leg guard regardless of brand. If you are buying a bolt-through wedge, check your leg guard for upper rivet holes on the back of the calf shield before ordering.
Should youth catchers wear knee savers?
Yes, starting around age 11 or 12. Younger catchers should focus on building proper squat mechanics first. Once a young catcher is logging real innings (more than 20 a season) and has clean stance fundamentals, the wedges add real value and protect developing knees. Use the youth size, not the adult.
Do MLB catchers wear knee savers?
Many do, including some of the most prominent catchers in the league. The exact percentage varies by team and season, but knee savers are standard equipment in MLB clubhouses, not novelty items. The same brands reviewed here — Easton, EvoShield, All-Star, and Mizuno — all have professional contracts with active catchers.
What is the single most important factor in choosing a knee saver?
Mount security. A wedge that slides during the game is worse than no wedge at all because it forces you to think about your gear instead of the pitch. Bolt-through models give you the most reliable mount, with strap backup as a redundant safety. Strap-only models are fine for casual use but require attention during long games. Pick the mount type that matches your willingness to adjust mid-game.
Bottom Line
Knee savers are not magic and they are not a crutch. They are a $25 to $35 piece of foam that can extend a catcher’s career, reduce day-after soreness, and let you stay in the squat without thinking about your knees. The All-Star System Seven is the best overall pick for serious catchers, the EvoShield Pro-SRZ is the most comfortable, the Easton III is the safest default, the Mizuno Samurai is the most refined for Mizuno users, and the Wilson C1K is the right call for budget-conscious youth players. Whichever you pick, mount it correctly, replace it when the foam compresses, and pair it with mobility work. Your knees in your forties will thank you.
