The Edge fins are the ultimate speed training fins, engineered to do it all. Through extensive testing at the FINIS Stroke Lab, the Edge fins were designed to optimize training without interrupting a natural kick cycle or compromising on comfort. The combination of 100% silicone and trademarked Smart Fin™ Technology reinforces a proper kick at high speeds, builds cardiovascular endurance and activates key muscle groups for a propulsive up-kick.
