Traditional fins are bulky, heavy, and uncomfortable. We created SlipFin Pro because swimmers need a comfortable, lightweight fin that supports good technique and allows for race-pace rhythm. SlipFin Pro slips over the top of the foot creating a suction that holds the fin in place. The patented design is intended to act like a natural extension of your foot. With your ankles and heels completely free, you get unmatched comfort, flexibility and power.Experience flow like never before. SlipFin Pro connects you to the water delivering smooth propulsion that reinforces the ideal bodyline and rhythm for every level of swimming.
