Tusa Fin Features

  ForcElast

A proprietary TPR compound molded into an advanced blade and foot pocket structure offers superior propulsion, efficiency and power transfer. ForcElast powers TUSA high performance fins like the SF-22 and FF-23.
Anatomic Fin Strap

TUSA open-heel fins are equipped with a newly designed Anatomic Fin Strap (AFS). The AFS is anatomically shaped to offer a balance of flexibility and control to increase comfort, power transfer and to significantly reduce heel slippage found in many standard flat fin straps.
Propeller Technology

The SF-8 and FF-9 X-Pert Zoom split fins employ Propeller-Fin™ Technology, which delivers ultra-high performance with a low amplitude rapid flutter kick. As the fin moves through the water its two wing-shaped surfaces create lift and forward propulsion like a propeller. Any water travelling over the top of the blade is funnelled into and out of the split between the blades. Efficiency is increased while drag and effort is reduced.
Angled Blade Design (A.B.D.)

TUSA's Angled Blade Design is employed on the SF-6 and SF-8 fins. A standard flat fin inhibits propulsion solely by fault of design. An angle between the heel of the foot and the calf of the leg remains when the leg is extended to kick. This angle causes 10% of the propulsion to be lost. The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.
EZ Strap and Buckle System

TUSA's EZ strap and Buckle System allows fins to be quickly and easily adjusted with minimal effort. Adjustment can be made while the fins are worn, allowing for a precise fit and ease of removal when necessary.
