C4 Umberto Pelizzari Sideral Blando – Performance with ecological awareness
The C4 Umberto Pelizzari Sideral Soft Fins pay tribute to a freediving legend, combining innovation, sustainability, and high performance. Made with the revolutionary #tide material, 100% recycled from ocean plastics, these fins offer efficient propulsion, technical design, and a total commitment to the environment.
Winners of the "Best Choice 2024" award from Apnea Passion, the Sideral Plata stand out as the best technopolymer fins on the market. Their soft blade and exclusive design profile allow for a fluid, precise and silent movement, ideal for prolonged freediving and discreet spearfishing.
The set includes the anatomic 250 shoe, lightweight (only 250 g), comfortable and highly efficient, which transfers foot energy to the blade with great precision thanks to its rigid sole and soft upper structure.
