SEAC Unisex Adult F1 Ultralight Diving Fins 730 g for Maximum Performance when Diving, Adjustable Strap, Yellow, 37/39

Extra light: Seac F1 diving fins offer excellent performance with minimal weight. At just 730 grams per fin, a reactive thrust is created that corresponds to heavier fins, but requires less effort. Extra durable: the rigid sections of the fin blade are held together by a special network of ultra-flex technopolymers. This special structure has high impact resistance even at low temperatures, and the rib guards prevent abrasion. Stable fit: the rubber of the foot part of the Seac diving fin F1 as well as the easily adjustable strap stabilise the fit and hold the fin on the foot. The sole is non-slip and has rubber profiles. From XS to XL | Seac F1 fins are available in 4 sizes (shoe size 34 to 45) (XS/S = 34/36; S/M = 37/39; M/L = 40/42; L/XL = 43/45) High performance: the Seac F1 fins represent the quality and performance typical of the Seac brand in underwater sports and offer functions that are usually reserved for professional fins, although they have been developed for recreational sports.
