The TUSA HyFlex Vesna fin builds on the original Vesna SF-0101 platform and adds the TA-0915 universal bungee strap, which fits all sizes and can be fitted to most open-heel fins. The elastic strap holds the foot without manual adjustment, and a comfort-flex hinge and rubber heel cup keep the fin seated securely during the kick cycle.
A pivot blade design allows the blade to hold a more effective angle through the stroke than a fixed blade, producing propulsion with less resistance and helping maintain drive across the full kick. The result is a fin that reduces the energy needed per kick, which suits longer dives and divers who want efficiency over raw power.
