Freediving fins and fin parts, mostly from C4 Carbon: long-blade carbon fins such as the Umberto Pelizzari Aurea and Volare T700, replacement blades, foot pockets from C4 and Mares, and small fin accessories.
How to choose: pick the blade stiffness (soft, medium or hard) by your weight and the depth you dive, then a foot pocket that fits snugly with the socks you wear. Blades and foot pockets are sold separately, so a worn part can be replaced without buying a whole fin.
