ForcElast
A proprietary thermoplastic elastomer (TPE) compound precisely positioned in an advanced blade and foot pocket structure. ForcElast delivers superior propulsion, efficiency and speed even with moderate power input. ForcElast technology is found in TUSA high performance fins like the SF-22 and FF-23.

Angled Blade Design (A.B.D.)
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 approximately 10% of the propulsion to be lost. The Angled Blade Design accommodates for this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.
