Freediving fins UP Sideral

Umberto Pelizzari. This mythical name and not much more would be enough to describe these fins. Tens of thousands of hours spent training, an impressive series of World Records in Constant Weight make Umberto an absolute reference when it comes to knowledge and experience in the use of freediving equipment. The new UP fins featuring technopolymer blades and 250 foot pockets are the result of the close collaboration between Umberto and C4. The Technopolymer Blade Fin has been created by using the most recent plastic moulding technologies. Performance, which has always been a real obsession for Umberto, is at the basis of this project. Foot pocket 250 The UP fins feature the new 250, the latest evolution of the fin foot pocket created by C4. Thanks to the use of a TPE 75 ShA polymer overmolded on a rigid sole, the 250 foot pocket transmits energy from the foot to the blade in the best possible way, resulting in highly efficient fins. The design of the geometries has allowed to use minimum thicknesses resulting in a reduction of the weight of the 250 footpocket in size 41/42 to just 250gr. Performance The reduced mass (weight) of the 250 footpocket minimises the energy required for movement, thus allowing the diver to save considerable energy and consequently reduce muscle fatigue. The connection between the foot pocket and the blade, thanks to the internal sole, is rigid and solid, and transmits the force to the blades efficiently. The assembly of the blade on the footpocket without side horns, already created by C4 in 2006, allows an elastic bending of the blade along its entire length.
