C4 Carbon Umberto Pelizzari UP Medium Stiffness Freediving Fins with 350 Foot Pockets, Technopolymer Blade, Unisex-Adult

Experience professional-grade freediving performance with these exceptional Umberto Pelizzari UP fins featuring C4 350 footpockets. These technopolymer blade fins represent the pinnacle of diving innovation, developed through extensive collaboration with world record holder Umberto Pelizzari. The fins boast over-molded water rails with precise dimensions for optimal water control and minimal lateral sliding. With a total fin length of 35.8 inches and a specialized 32-degree blade angle, these fins deliver superior propulsion and efficiency. The unique whale tail-shaped blade tip and strategic ribbing pattern enhance performance, while the lightweight design - under 2.6 pounds per pair - reduces fatigue during extended dives. The fins feature a distinctive smooth central band that widens from footpocket to tip, complemented by carbon fiber-look side panels. Built with premium materials and advanced molding technology, these fins set a new standard for serious freedivers seeking uncompromising performance and precision in their equipment. Thanks to the use of a TPE 75 ShA polymer, the energy transmission of the 350 footpocket to the blade is increased, thus obtaining highly efficient fins. The study of the geometries has allowed us to obtain minimum thicknesses, allowing the weight of the 350 footpocket in size 41/42 to be reduced to just 350 grams. PERFORMANCE Reduced thicknesses that increase comfort and do not cause foot pain. Attachment of the blade without footpocket horns. The assembly and disassembly of the blade is quick and simple and the size is optimal in case of air travel.
