HammerHead Tuff Socks are created from a durable 3mm neoprene and are used to protect feet from abrasions while also keeping your feet warm. An extra long open cell seal and anatomical ankle cut prevents unwanted water from seeping in. Tiny grip sharks on the sole of the socks give you traction for maximum power transfer on the downstroke of your kick. Those tiny grip sharks on the soles also help keep you upright on slippery surfaces.
