Volleyball insoles for jumping, blocking and court movement
Springbak® Springsoles are a thin 3/32-inch resilient layer used with your existing factory insole rather than replacing it. They are designed for the movements volleyball repeats — approaches, blocks, landings and lateral court movement — where the material is built to return to shape between reps instead of packing out like foam. Coaches at Minnesota, Nebraska, BYU, UC Santa Barbara and the New Zealand men's national team have all put them on their rosters. The layer is designed to minimize changes to your shoe's original fit — confirm fit in your own footwear.

What volleyball demands of your feet
- Approach jumps and block jumps, over and over, in the same spot
- Repeated hard landings on an unforgiving court
- Lateral defensive movement and floor work
- Multi-match tournament days
Why Springsoles fit this sport
Designed for repeated jump volume
The resilient layer is designed for repeated approaches, blocks and landings; the standing force-plate test did not measure landing-force reduction or late-match performance.
Insoles for volleyball shoes without bulk
At 3/32", these volleyball shoe inserts are designed to minimize changes in shoe fit; confirm the actual fit and ankle support in your own court shoes.
Returns to shape between jumps
The resilient material returns to shape between repetitions instead of packing out like foam. How each jump feels depends on the athlete — late-match performance was not measured.
The technology, materials and four U.S. patents behind Springsoles are detailed on How it works.

Will it fit my volleyball shoe?
Pick the shoe you actually play in and see how a Springsole goes in, how much to trim, and what the layer is designed to leave in place. These are the eleven court shoes we get asked about most.
Every verdict assumes a stock shoe. Try the Springsole untrimmed first. If the liner is removable, put the Springsole underneath it. If a lightly glued liner releases cleanly with a gentle pull, place the Springsole underneath; if it tears, stretches, deforms or resists removal, stop and put the Springsole on top. Never force out a firmly bonded or stitched liner. Trim only the toe or forefoot if needed for a flat fit, remove a very small amount at a time, and recheck after every trim. Never trim the heel or unnecessarily narrow the sides.
Every fit verdict is an expectation, not a guarantee: try the Springsole untrimmed first, then confirm flat placement, lockdown, lace tension and ankle-brace fit in your own pair before playing.

Fit, trim & sizing FAQ
Questions the fit checker answers
What does the "fits as-is" verdict mean for my volleyball shoes?
+
"Fits as-is" means to try the stock model with the 3/32" Springsole untrimmed first. "Fits — trim the toe" means a small toe or forefoot trim may be needed only after that first fit check. "Check your pair first" means the liner may vary by model year.
How much do I trim, and where?
+
Try the Springsole without trimming first. Trim only if needed for a flat fit, starting at the toe/forefoot and removing a very small amount at a time. Do not trim the heel and do not unnecessarily narrow the sides. Recheck the fit after every small trim.
Does the Springsole go above or below my insole?
+
Try the Springsole without trimming first. If the factory liner is removable, remove it and place the Springsole underneath it. If the liner is lightly glued, gently pull to see whether it releases cleanly; if it does, place the Springsole underneath it. If the liner begins to tear, stretch, deform, or resist removal, stop and leave it in place. Put the Springsole on top instead. Never force out a firmly bonded or stitched liner.
What size Springsole do I order for my volleyball shoes?
+
Order by your US shoe size on the Shop page — US men's sizes run 6/7, 8/9 and 10/11, and US women's sizes run 7/8, 9/10 and 11/12, with each pair covering a size range. Try it untrimmed first; trim only the toe or forefoot in very small amounts if needed for a flat fit. Snug low-profile court shoes are the most common trim case: take your normal size and trim the toe to your outline.
Will adding a layer change how my volleyball shoes fit?
+
The thin 3/32-inch layer is designed to minimize changes in shoe fit. Confirm the actual fit, lace tension and ankle-brace fit in your own volleyball shoes before playing.
My model is not in the list — can I still use them?
+
Yes. The picker covers the models we are asked about most. Try the Springsole without trimming first. If the factory liner is removable, remove it and place the Springsole underneath it. If the liner is lightly glued, gently pull to see whether it releases cleanly; if it does, place the Springsole underneath it. If the liner begins to tear, stretch, deform, or resist removal, stop and leave it in place. Put the Springsole on top instead. Never force out a firmly bonded or stitched liner. If you are unsure, email info@springbak.net or call 951-277-3000 with your exact model.
Insole vs. midsole layer
Volleyball shoe insoles: full-length replacement insoles vs. a Springbak® midsole layer
Almost every performance insert on the market is a replacement insole: you pull your shoe's sock liner out and put theirs in instead. Springbak® works the other way — it adds a thin 3/32-inch resilient layer while your factory insole stays in use, subject to confirming the actual fit in your own shoe. For a hitter that matters twice over: your court shoe was engineered around its own footbed, and you land on it through every approach, block and landing in a match.
| Product category | What it is | Where it sits | Typical thickness | What it does with impact |
|---|---|---|---|---|
| Springbak® Springsoles | A 3/32" resilient 1,4-polybutadiene sheet, trimmed only if needed for a flat fit, made in the USA and covered by four U.S. patents. | Added under your shoe's own insole (or on top of a sewn-in pad). Your factory insole stays in the shoe. | 3/32 in (≈2.4 mm), even from heel to toe | Stores and returns energy inside the ground contact, and the material springs back to shape between reps. |
Sources | ||||
| Carbon-plate performance insoles (e.g. VKTRY VK Insoles) | A moulded, sport-specific carbon-fiber plate with a foam top cover, fitted by shoe size and athlete weight. | Replaces your shoe's insole — the factory sock liner comes out and stays out. | Full-length insole stack; considerably taller than a bare midsole layer | Flexes and rebounds as a plate. Because it replaces the insole, it also changes footbed shape and internal shoe volume. |
Sources | ||||
| Cushioned replacement insoles (e.g. Spenco) | Full-length foam, gel or PU insoles built around comfort, arch shape and pressure relief. | Replaces your shoe's insole. | Typically several millimetres, often heel-loaded | Designed primarily to absorb and spread impact rather than return it. |
Sources | ||||
| Viscoelastic shock-absorbing insoles (e.g. Sorbothane) | Full-length inserts made from a viscoelastic polymer specified for shock absorption and vibration damping. | Replaces your shoe's insole. | Full-length insole thickness, varies by model | Damps impact energy by design — that is the stated purpose of a viscoelastic material. |
Sources | ||||
| Structured support insoles (e.g. Superfeet, custom orthotics) | A rigid or semi-rigid shell with arch and heel posting, sometimes prescribed by a practitioner. | Replaces your shoe's insole. | Full-length shell plus posting | Built to control alignment and position the foot, not to give energy back at contact. |
Sources | ||||
| Your factory insole / sock liner | The die-cut foam liner your shoe was designed and fitted around. | Already in the shoe — and with Springbak®, it stays there. | ≈1–5 mm depending on the shoe | Comfort and fit layer with essentially no engineered energy return. |
Sources | ||||
We add, we don't replace
Springbak® is not a new insole and not a new shoe. The thin 3/32-inch layer is designed to minimize changes to your shoe's original fit and feel — confirm fit, lockdown and brace compatibility in your own footwear.
Sized for your shoe, trim only if needed
One pair covers a size range and is trimmed at the toe to your own foot outline. Try the Springsole untrimmed first — the 3/32-inch layer is designed to minimize fit changes. Confirm flat placement, lockdown, lace tension and ankle-brace fit in your own pair before playing.
Return, not absorb
Cushioning products are engineered to soak impact up, while Springbak®'s material is chosen to hand energy back inside the contact — that is its intended function. Separately, Weber State force plate testing measured standing stability: it took more than twice the force to displace a person standing on Springsoles. That test did not measure energy return.

Three coaching legends put Springsoles on their rosters
These are attributed coach reports and observations from teams that used Springsoles. Hugh McCutcheon's report comes from his BYU speed-gun session; the other published quotes remain each coach's own observation and appear exactly as Springbak has always run them.

Hugh McCutcheon
Minnesota / USA Volleyball
Former head coach, University of Minnesota volleyball; former USA Volleyball head coach; assistant coach at BYU when he tested Springsoles
Olympic gold (2008 men) and silver (2012 women) as USA head coach
“While an assistant coach at BYU I tested spiking speed of our men's volleyball team with a speed gun. After an hour of testing it became apparent that they were hitting 5% faster in Springsoles.”
Hugh McCutcheon reported the approximately 5% faster spiking figure from that speed-gun session at BYU; it was not a vertical-jump measurement.

John Cook
Nebraska volleyball
Former head coach, University of Nebraska volleyball
Four NCAA national championships at Nebraska
“There is no doubt in my mind after testing and hearing the athlete's feedback that your innersoles help our athletes jump higher and move quicker.”
A coach's reported observation from his program's own testing and athlete feedback — not a laboratory measurement. Individual results vary.

Carl McGown
BYU men's volleyball
Former head coach, BYU men's volleyball (1990–2002); longtime USA Volleyball national-team coach
Two NCAA national championships at BYU (1999, 2001); Volleyball Hall of Fame
“We love Springsoles from Springbak®. We have been using them for an explosive team.”
In memoriam — Carl McGown passed away December 30, 2016, at age 79. A coaching icon whose technique teaching shaped generations of American volleyball.

Weber State force plate testing
The measured force-plate result and its volleyball application
Measured laboratory result: Weber State University force-plate testing found that it took more than twice the force to displace a person while standing on Springsoles. That test measured standing stability, not vertical-jump height, landing forces, injury prevention or late-match performance. Volleyball application: the resilient Springsole layer is designed for the plants, jumps, landings and changes of direction used in play; this is a product explanation, not an outcome measured by the force-plate test.
- Measured: more than twice the force was required to displace a person standing on Springsoles.
- Product application: a resilient layer beneath the foot during approach steps and landings.
- Material explanation: the elastomer is designed to return to shape between repetitions instead of packing out like foam.
See the full breakdown on Proof & testing.
Force-Plate Stability Study
In force-plate testing, subjects standing on Springbak® Springsoles showed more than twice the overall resistance to being pushed from their position.
This was a standing stability measurement. It did not measure vertical-jump height, landing forces, injury prevention, or late-match performance.
For volleyball, Springbak® applies that resilient platform beneath the foot during plants, jumps, landings, and changes of direction; those applications are product explanations, not outcomes measured in the force-plate test.
Results are from the force-plate testing described in U.S. Patent No. 6,589,630 B1. Individual results vary.

Installing a Springsole in a volleyball shoe (20 seconds)
Filmed courtside in two close-up scenes: the factory insole lifts out, the black Springbak-branded Springsole slides in flat against the midsole, then your own insole goes right back in on top of it and is pressed flat. The video shows a shoe with a removable liner: the Springsole is tried untrimmed, placed underneath, and checked flat. Other liner types follow the fitting steps below.
Full transcript
- 0:00
- This example shoe has a removable liner. First try the Springsole untrimmed, then lift the grey factory liner out and set it beside the shoe.
- 0:03
- Step 2 — Insert: hands slide the black Springbak Springsole — yellow Springbak script and springbok logo facing up — into the shoe, flat against the midsole, lining the heel of the insole up with the heel of the shoe.
- 0:06
- Thumbs press the black Springsole smooth from heel to toe so it lies flat — no bubble, no wrinkle, no curled edge.
- 0:10
- Step 3 — Layer on top: the grey factory insole is lowered back into the shoe so it sits directly on top of the black Springbak Springsole.
- 0:14
- Fingers press the factory liner flat. Trim only if needed, removing a very small amount from the toe or forefoot and checking after each cut. Never trim the heel.
- 0:17
- The finished stack: black Springbak Springsole on the bottom, your own insole on top, and the shoe laced up snug. Under a minute per shoe.
FAQ
Volleyball insoles — frequently asked questions
Will volleyball insoles help my approach jump?
+
Springbak is designed to return energy you generate rather than create force. Some hitters report feeling more spring late in matches; that is attributed user feedback, not a measured endurance result. Hugh McCutcheon reported approximately 5% faster spiking speed from his BYU speed-gun session. Separately, Weber State laboratory force-plate testing found that it took more than twice the force to displace a person while standing on Springsoles; that test did not measure vertical-jump height. Individual results vary.
What size Springsole should I order for volleyball?
+
Order your regular court-shoe size and try the Springsole untrimmed first. If needed, trim only the toe or forefoot in very small amounts and recheck after every cut. Never trim the heel or unnecessarily narrow the sides.
Do they work with ankle braces?
+
The thin 3/32-inch layer is designed to minimize changes in shoe fit. Confirm the actual lace tension and ankle-brace fit in your own volleyball shoes before playing.
Will they raise me out of my volleyball shoes?
+
The 3/32-inch layer is designed to minimize changes in shoe fit. Confirm the actual fit, lace tension and ankle-brace fit in your own volleyball shoes before playing.
How do I install them in court shoes?
+
Try the Springsole without trimming first. If the factory liner is removable, remove it and place the Springsole underneath it. If the liner is lightly glued, gently pull to see whether it releases cleanly. If it does, place the Springsole underneath it. If the liner begins to tear, stretch, deform, or resist removal, stop and leave it in place. Put the Springsole on top instead. Never force out a firmly bonded or stitched liner. Trim only if needed for a flat fit, starting at the toe/forefoot and removing a very small amount at a time. Do not trim the heel and do not unnecessarily narrow the sides. Recheck the fit after every small trim.
How many jumps will they last?
+
The patented elastomer is chosen for resilience, not foam-style compression, so it returns to shape between reps instead of packing out. Programs typically run a pair through a full club and school season of jump volume.
Do they help liberos and defensive specialists, or just hitters?
+
Every position loads the forefoot. Springbak is designed for the lateral push-offs, low lunges and repeated floor work defensive players perform. The Weber State result measured resistance to displacement while standing; it did not directly measure cutting or vertical jumping.
Do they work for both indoor and beach players?
+
Indoor players get the full benefit in court shoes. Beach players use them in trainers for lifting, approach work and conditioning, since sand play is barefoot.
Are Springsoles legal for high school, club and college competition?
+
Yes. They are an insole that sits inside the shoe — not a device attached to it — and add no external spring. They have been used on rosters at Minnesota, Nebraska, BYU, UC Santa Barbara and the New Zealand men's national team.
How much do volleyball insoles cost and where do I buy them?
+
Every pair of Springbak® Springsoles is made in the USA, and covered by four U.S. patents. Pick your size on the shop page and checkout completes on the springbak.net cart. Team and program pricing is available through the bulk-order form.
Do volleyball insoles actually improve performance?
+
An insole cannot create force; Springbak is designed to return part of the energy an athlete produces. The evidence here is distinct: Weber State University laboratory force-plate testing found that it took more than twice the force to displace a person while standing on Springsoles. Separately, coach Hugh McCutcheon reported approximately 5% faster spiking speed during his BYU speed-gun session. Neither finding directly measured vertical-jump height, landing-force reduction, injury prevention or late-match performance. Individual results vary.
Do vertical jump insoles actually make you jump higher?
+
No insole creates force — jump height comes from the athlete, and the current evidence does not directly measure vertical-jump height. Springbak® Springsoles are designed as a thin, resilient layer that returns to shape under the athlete's existing insole; the 3/32-inch layer is designed to minimize fit changes — confirm the actual fit in your own pair. The separate documented findings are Weber State University's force-plate measurement (it took more than twice the force to displace a person while standing on Springsoles) and Hugh McCutcheon's reported approximately 5% faster spiking speed from his BYU speed-gun session. Neither test directly measured vertical-jump height, and individual results vary.
How do I choose volleyball insoles?
+
Work through four things in order. Thickness: anything over about 1/8" changes your court-shoe fit, so look for a thin layer — Springsoles are 3/32". Resilience: the material has to return to shape between jumps. Evidence: ask what was measured, in which lab, by whom. Fit path: try the Springsole untrimmed first. Put it under a removable liner. If a lightly glued liner releases cleanly with a gentle pull, place it underneath; if the liner tears, stretches, deforms or resists removal, stop and put the Springsole on top. Never force out a firmly bonded or stitched liner. Trim only the toe or forefoot if needed for a flat fit, remove a very small amount at a time, and recheck after every trim. Never trim the heel or unnecessarily narrow the sides.
What are the best insoles for volleyball players?
+
When you shop for volleyball performance insoles, look for a thin, high-resilience layer that sits with your factory liner rather than replacing it. The 3/32-inch Springsole is designed to minimize changes in shoe fit, but players should confirm lockdown, lace tension and ankle-brace fit in their own footwear. Full-length replacement insoles change the fit of a low-profile court shoe and are usually built for arch support, not energy return. Springsoles were adopted on rosters at Minnesota, Nebraska, BYU, UC Santa Barbara and the New Zealand men's national team.
Are performance insoles legal under NFHS, NCAA and USA Volleyball rules?
+
Insoles are legal because they sit inside the shoe as part of the footwear, and Springsoles add no external spring, plate or device attached to the shoe. Rules bodies restrict what is attached to or worn outside a shoe, not what liner you play on. If your conference or state association has its own equipment approval process, show them the insole itself — it looks and installs like a footbed.
What is the difference between a Springbak® layer and a carbon-plate insert?
+
A plate insert is rigid and full-length: it stiffens the shoe, adds height and changes how the forefoot bends, which is why plate products are thick and shoe-specific. A Springsole is a 3/32" patented elastomer layer designed to preserve your shoe's own geometry while returning energy through the material instead of a stiff lever; confirm the actual fit in your own pair. For volleyball, where court shoes are deliberately low and ankle braces are common, keeping changes to the original fit to a minimum is usually the deciding factor.

Springbak EU Size
European sizing — trim only if needed

QuantityWe could not confirm size 38 / 40 just now.
View current price on springbak.netEU questions
Which EU size should I order?
Order your normal EU shoe size. This listing covers EU 38/40, 41/42 and 43/45. If you fall between two ranges, take the larger one. Try it untrimmed first, then trim only the toe or forefoot in very small amounts if needed for a flat fit.
How do these compare to other sizing standards?
EU 42 is roughly US men’s 8.5 and UK 8; EU 39 is roughly US women’s 8.5. All four listings are the exact same patented 3/32-inch Springbak® Springsole at the same price — only the size scale printed on the package changes. The current price is shown live from our store.
Will Springsoles fit court shoes, cleats and trainers bought in EU sizing?
Yes. Try the Springsole without trimming first. If the factory liner is removable, remove it and place the Springsole underneath it. If the liner is lightly glued, gently pull to see whether it releases cleanly; if it does, place the Springsole underneath it. If the liner begins to tear, stretch, deform, or resist removal, stop and leave it in place. Put the Springsole on top instead. Never force out a firmly bonded or stitched liner. Try the Springsole without trimming first. Trim only if needed for a flat fit, starting at the toe/forefoot and removing a very small amount at a time. Do not trim the heel and do not unnecessarily narrow the sides. Recheck the fit after every small trim. At 3/32 of an inch, Springsoles fit court shoes, cleats and trainers bought in EU sizing with minimal added thickness.
How do I check out and what if the size is wrong?
Choosing a size here opens the secure Springbak® cart on springbak.net with this listing and your quantity already added. Payment, shipping and exchanges are handled there by the Springbak® team — email info@springbak.net or call 951-277-3000 and we will get you the right pair.

Which UK size should I order?
Order your normal UK shoe size. This listing covers UK 5/6, 7/8 and 9/10. If you fall between two ranges, take the larger one. Try it untrimmed first, then trim only the toe or forefoot in very small amounts if needed for a flat fit.
How do these compare to other sizing standards?
UK sizing runs about 1 size below US men’s and 5 sizes below EU (UK 8 ≈ US men’s 9 ≈ EU 42.5). All four listings are the exact same patented 3/32-inch Springbak® Springsole at the same price — only the size scale printed on the package changes. The current price is shown live from our store.
Will Springsoles fit boots, trainers and court shoes?
Yes. Try the Springsole without trimming first. If the factory liner is removable, remove it and place the Springsole underneath it. If the liner is lightly glued, gently pull to see whether it releases cleanly; if it does, place the Springsole underneath it. If the liner begins to tear, stretch, deform, or resist removal, stop and leave it in place. Put the Springsole on top instead. Never force out a firmly bonded or stitched liner.

Not just for competition
Balance and stability off the court
The same patented material shows up in stability testing, not just performance testing. On a force plate at Weber State University it took more than twice the force to push a person off the plate while standing on Springsoles. If you or a parent are on your feet all day, read Springsoles for seniors: balance and stability all day on your feet. And if you play the fastest-growing court sport in the country, see pickleball insoles for court shoes and hard-court play.
Want the grounded-stance answers — how the force-plate result translates into balance, base of support and functional strength? Read the Springbak® balance and force-plate proof.
