Built from impact-resistant EVA, the Seac Propulsion Sling Strap Fin delivers serious thrust without the muscle fatigue — a blade-length channel directs water straight off the tip instead of letting it spill out the sides. The anatomical foot pocket locks in with the blade for a natural kick and less ankle strain on long swims, while the color-matched sling strap adjusts easily over wetsuit or drysuit boots and gloved hands alike. Tough in cold water and built to resist UV, stress cracks, and the elements, it's ready for everything from reef dives to demanding technical swims. Available in white, blue, yellow, and black across three sizes (S/M, M/L, L/XL).Pairs well with: Seac dive boots, a dive mask, and a snorkel. Show more
