SCUBAPRO's “boot-fit” design features a replaceable, self-adjusting bungee heel strap that slips easily over boots, ideal for divers who frequently negotiate rocky shore entries. The fins' ultra-strong 100% Monprene construction won't delaminate, break, or tear even after years of use, making it ideal for long-term, heavy-duty use. Performance features like a 25-degree pre-angled blade and power bars on the underside of the rail make the fins fast, powerful, stable, and maneuverable with minimal effort. Bring the fins to your favorite tropical waters with its compact, lightweight design, which easily fits in AITA carry-on compliant luggage. Driven to constantly innovate and improve the diving experience, SCUBAPRO builds high-quality equipment for the work, sport, and lifestyle of people whose passion is found below the surface. Power Bars on the underside of the rails prevent over-flex to maintain the optimum angle of attack under high-load conditions. In-water performance delivers speed, power, stability and maneuverability with a minimum of effort. Fins fit easily in IATA carry-on compliant luggage for divers who like to travel the world. Skegs mounted on blade ends minimize sideslip and maximize stability. Black and blue fins come with silver skegs, all other colors come with black skegs.
