Insoles by sport

Performance insoles for your sport

Springbak® Springsoles are 3/32-inch patented inserts fitted under a removable liner or on top of a firmly bonded or stitched liner. Pick your sport for the movement demands, fitting notes and training that go with it.

Not competing? Springsoles are just as much about footing as speed — see balance and stability insoles for seniors on their feet all day, backed by the Weber State University force plate 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.

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.
