Aqualung / US Divers HingeFlex Fins
Get twice the power with half the effort from your swimming fins with the U.S. Divers® Hinge Flex Fins for Adults. These fins utilize U.S. Divers' Energy Return System (ERS) pivoting fin blade technology to save energy and maximize power from every kick.
Hinge Flex fins use heavy duty rails and pivoting design to store energy on the down stroke, with the blade pivoting back to normal and releasing that energy just prior to the upstroke.
- Energy Return System (ERS) pivoting fin blade technology saves energy and maximizes power from every kick
- Cross beam construction
- Made of premium high memory polypropylene
- Pivot Tech design: More power than a full-sized fin from a travel-sized fin
- Easy-to-adjust, ergonomic buckle and strap system automatically pivots for perfect fit
