These open-heel fins are perfect for local diving and generally colder temperature water because they are to be used with dive boots. They have a powerful, compact blade and they come in a wide selection of colours. The rubber side ribs minimize energy lost to spill-over. The Mid-foot Flex Joint reduces the strain on ankles and toes and allows the entire foot to be used. This results in extreme comfort.

Aqualung Express SS Adj Fin features:

  • The armadillo membrane at the base of the blade provides a power boost on every kick.
  • The rubber side ribs channel water down the fin, minimizing wasted energy.
  • A Mid-Foot Flex Joint attaches the blade to the side of the foot pocket maximizing energy transfer and reducing the strain on the ankles and toes.
  • The streamlined foot pocket provides an ergonomic fit for excellent energy.
  • Anti-slip rubber pads on the bottom of the foot pocket give traction for moving around.
