IST Sumi Fins
The IST Sumi Fins are designed to produce efficient fast propulsion for the diver along with producing an easy pair of fins to kick maintaining excellent momentum through the water.
The fin’s foot pocket has been created to the best criteria following extended research. The adjustable foot pocket means that the diver can adjust it to the perfect fit making it a comfortable fin to wear. On the top of the fin blade there are 6 water channelling guides meaning that water is directed backwards providing the best kicking efficiency through its 22º blade to foot angle.
