The Edge · Springbak® Performance Desk
Written for athletes who already do the work — speed, vertical, mechanics, recovery, and the ground beneath all of it. Every piece traces a sport demand back to the contact between your foot and the floor.
LatestTrack & Field · Mechanics
A hurdle touchdown lands and re-accelerates in the same instant. A jump takeoff converts a full approach in one plant. Both are decided by what happens under the foot.

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.

The Edge is Springbak's performance desk — written for athletes and coaches who already do the work. Every piece connects a specific sport demand (a first step, a block start, a fourth quarter) back to what happens under the foot on the ground.
They are written by the Springbak Performance Desk and grounded in force plate testing conducted at Weber State University and in the four U.S. patents Springbak holds on performance-enhancing shoe components.
