The HYDRO OG are the original swim fins, great for belly riding and swimming. Swim fins are PERFECT if you want to progress your bellyboarding into deeper water and bigger waves. We recommend that all riders should have a pair of these.... Swim fins allow you transmit the maximum amount of power into kicks whilst maintaining control and comfort. This allows you to catch waves earlier when on your Dick Pearce & Friends bellyboard. See more info on how to bellyboard. Materials Extremely comfortable with a larger foot pocket.

Features: • 100% Floating Rubber • V Rail Design for maximum speed and traction. • Drain holes ensuring water & sand are quickly flushed. • Contour Ankle strap designed to ensure maximum comfort. • Perfect for body boarding and surf swimming.
