Finis Fins from Edge

HIGH SPEED FLIPS TheEdge is a high speed fin developed by Finis. After extensive testing in the Finis Stroke Lab, the Edge fins have been designed to enhance training without interfering with the natural kick cycle and swimmer's comfort. The combination of the use of 100% silicone and Smart Fin Technology improves footwork at high speeds, enhancing cardiovascular work and activating the muscle groups involved in kick propulsion.
