The Edge fins are designed to improve technique and give your legs a real workout. It takes power to push these fins through the water, which results in building strength and endurance. The side rails on the fin activate your hips and quadriceps – enforcing a proper kick that starts at your hips  and not your knees. This motion is great for glute and hamstring development.

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.

Made of 100% silicone, Edge fins will mold to your feet over time, like breaking in a new pair of shoes.
