Edge Fins.

Learn to kick from the hip.  FINIS Edge Fins are designed with technique-focused side rails to activate your hips and quadriceps.  This will enforce a proper kick that starts at your hips and not your knees.  

WHAT IT DOES  
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. This motion is great for glute and hamstring development. They can be worn during aerobic and anaerobic training to increase endurance and speed.

HOW IT DELIVERS 
Edge Fins are a great teaching tool for swimmers of all levels to support and improve proper kick technique.  The proprietary blade angle is designed to feel like a natural extension of the foot.  The open toe design allows for a snug fit and prevents chaffing.  Made of 100% silicone, Edge fins will mold to your feet over time, like breaking in a new pair of shoes. Size up if you are between sizes or have wide feet.

How do they roll in the real world?

"These had been recommended to me for training. They are true to size and are lightweight. Easy to get on and off. Excellent for helping in training but are also really good fun too. Highly recommend." - EmSaUl
