Boot-Compatible Open-Heel Design: Designed for use with dive boots (booties). Sizing accounts for boot wear, so choose a slightly larger size than full-foot fins for a secure and comfortable fit. Powered by PuRiMaX Polyurethane Blade System: Delivers superior snap and flexibility, maximizing propulsion with every kick while minimizing leg fatigue. Performance-Focused Foot Pocket Design: Features a multi-compound “Comfort Foot Pocket” that enhances fit, reduces pressure, and improves power transfer to the blade. Universal Bungee Strap System: Comes standard with TUSA’s TA0902 bungee strap for quick and secure adjustments, allowing fast donning and doffing even with gloves. Travel-Ready Hyflex System: Innovative offset blade and modular design allow for compact packing—ideal for travel divers seeking top-tier performance in a portable fin. The TUSA SF0104 Hyflex Switch is powered by PuRiMaX “Polyurethane Blade System”. The Polyurethane blade provides a quick “snappy” response to the diver’s every movement. TUSA’s unique “Vortex Generator” effectively reduces water resistance through the fin stroke normally found on traditional smooth blades. TUSA’s Multi-compound foot pocket increases power transfer to the fin blade. The TUSA Hyflex Switch is equipped with the new Universal Bungee Strap providing extraordinary comfort.
