| Springboost SpringBoost is revolutionizing athletic footwear with its use of dorsiflexion, which positions the heel lower than the ball of the foot. Based on seven years of research and testing at the Federal Institute of Technology in Lausanne, Switzerland, its Dorsiflexion Technology™ has been scientifically proven to recruit more muscle fibers – toning, lengthening and strengthening muscles with every step – while improving body alignment, vertical leap and explosive power.
