These WHALE Surf Fins come in two bold colour combos – black and red, and black and yellow – for maximum visibility in the water. Choose from three different sizes (XS, S and M). You’ll find a full overview of the measurements for each size in one of the images provided. Best of all, they’re made from silicone, which is softer than rubber for maximum comfort. These fins also feature a streamlined tail for strong diving and better stability, an anti-skid sole and a water outlet to reduce water resistance.
