Springbak® Springsoles
Explosive play starts beneath your feet
Springsoles are patented, 3/32-inch energy-return insoles. Try them untrimmed first; place them under a removable liner or on top of a firmly bonded or stitched liner. One pair, made in the USA.
Why Springsoles work
Energy return, not cushioning
A thin resilient layer gives your feet something to push into, so force you already produce comes back instead of dissipating into the shoe.
Grounded balance
In force-plate testing at Weber State, it took more than twice the force to displace a person standing on Springsoles.

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.
In plain English: they were harder to move. They could hold their ground better against a sideways push—exactly the kind of stability athletes need when planting, cutting, jumping, landing, and absorbing contact.
Springbak® gives the foot a more stable, responsive platform to work from inside the shoe.
Results are from the force-plate testing described in U.S. Patent No. 6,589,630 B1. Individual results vary.
