The Biofuse Fitness Fin by Speedo is a set of short fins designed to help improve kick technique as well as leg strength and ankle flexibility during swimming, making it an ideal swim training accessory. The Speedo Biofuse technology makes these swim fins super soft and flexible for excellent comfort when you are training. In a minimalist, open heel design for more "feel of the water".
Very pleased with product small and light and ver easy to use.
Smaller than I thought but for my first pair of fins they are idea. Very comfy.
