Performance Footwear Springsoles
Made in the USASpringbak® Springsoles — performance beneath your feet
Patented, ultra-thin Springbak® Springsoles add a 3/32-inch resilient layer to compatible athletic and everyday footwear. Placement depends on the shoe’s factory liner: try the Springsole underneath a removable liner when it releases cleanly, or place it on top when the liner stays in place. Confirm actual fit in your own footwear.
Resilient 1,4-Polybutadiene
The Springbak layer is designed to compress under load and return toward its shape. Energy return is the intended material function, not a measured athlete-performance result.
Measured Standing Resistance
Weber State force-plate testing found that more than twice the force was required to displace a person standing on Springsoles compared with standing without them.
Four U.S. Patents
Four U.S. patents cover Springbak shoe-component technology and methods.
Weber State standing test
More than twice the force to displace a standing subject
Weber State force-plate testing found that more than twice the force was required to displace a person standing on Springsoles compared with standing without them. This was a standing resistance-to-displacement measurement. It did not directly measure walking stability, gait, fall prevention, fall risk, pain, strength improvement or performance during everyday movement.
Force-Plate Stability Study
Weber State force-plate testing found that more than twice the force was required to displace a person standing on Springsoles compared with standing without them.
This was a standing resistance-to-displacement measurement. It did not directly measure sprint speed, jump height, balance during movement, fall prevention, pain, fatigue or sports performance.
Athletic and everyday uses are product applications, not outcomes measured in this force-plate test.
Results are from the force-plate testing described in U.S. Patent No. 6,589,630 B1. Individual results vary.

Take the Springbak® Challenge
Record a baseline, change one variable and re-test under the same conditions. Athlete Tools can log vertical-jump and sprint measurements so you can compare your own results. This is a personal self-test, not laboratory proof of a guaranteed performance improvement.
