The Tusa Imprex Duo Open Heel Fins feature Tusa's patented 'Angled Blade Design' and multi-compound foot pocket, increasing power transfer to the fin blade. The Tusa Imprex Duo also features a two material design for high performance and reinforced side-rails creating stability, for powerful propulsion without fatigue.
The fin's 'Angled Blade Design' (ABD) unlike a standard flat fin that 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. TUSA's Angled Blade Design accommodates this anatomical characteristic and ensures maximum efficiency throughout the kicking cycle.
Fins are equipped with TUSA's EZ Strap and Buckle System. TUSA's EZ strap and buckle system allow the 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.
The dual-material composite fin non-vented blade design provides high performance along with the multi-compound open heel foot pocket increases power transfer to the fin blade. Balanced flexibility gives powerful propulsion without fatigue!
ScubaLab Testers Choice and Best Buy 2021
A well-rounded kicker, the Imprex Duo took excellent and very good scores in every test category. The blade is angled 20-degrees from the foot pocket and has two soft channels that helped it kick easily and efficiently, taking very good scores in all kicking styles, including dolphin. Reinforced side rails kept the blade tracking straight during hard kicking and took the top score for stability in its category. The 14-inch blade proved to be highly maneuverable and scored very good for power vs. stress. "Control and responsiveness like an extension of my own foot," one tester commented. Outfitted with an easy-to-use adjustable strap, testers found it quick to don and doff. The ergonomic foot pocket took the only excellent score for fit and comfort in the test, and inspired tester comments like "super comfortable,"” and "light and comfy." With exceptional comfort and solid performance across the board, it’s no wonder that this fin was a favourite among test divers. What is surprising is that it offers all this at a cost below any other fin in its category. The Tusa Imprex Duo is our Testers Choice and Best Buy for open-heel fins.
