Finis CFYN Edge Fin
- Teaching tool for swimmers of all levels to support and improve their kick
- Technique focused side rails activate your hips and quadriceps— enforcing a proper kick that starts at your hips and not your knees
- Proprietary blade angle is designed to feel like a natural extension of the foot
- Open toe design allows for a snug fit and prevents chaffing. Size up if you are between sizes or have wide feet
- Made of 100% silicone, Edge fins will mold to your feet over time, like breaking in a new pair of shoes.
