The Crep Protect PORON Vive Insoles combine shock absorption and energy return in one advanced technology, featuring dynamic open-cell construction that instantly responds to every step. With over 55% ball rebound, they deliver powerful push-offs and quick, responsive movements while reducing and redirecting forces away from the foot. Designed with a “lift off” zone for maximum propulsion, these insoles provide consistent cushioning and resiliency to help maintain an energy-efficient stride and combat fatigue. They come cut-to-size in a pack containing one pair.
