Just imagine...a high performance fin you can also walk in when entering and exiting the water...who knew? The days of dragging your fins in and out of the water are finally over! Dynamic Scuba Fins (or "flip fins") are a totally new class of fins. Take them out once and you will never go back to traditional fins. The revolutionary and durable Aqua-Hinge Mechanism and highly efficient non-vented blade design provide an essential combination of performance and safety for Scuba divers at all levels. For swimming, no other open heel fin can match the power and comfort provided by the Amphibian, which features a prominent central web configuration contributing to increase propulsion and reduced load required during sustained kicking. A natural evolution within the dive industry, the Amphibian Fin System is designed to be strapped on prior to entering the water and removed after exiting. The heavy duty springs push the soft blade webbing up to ride gently against the shin while on the surface. This makes walking, climbing boat ladders and other movements as easy as wearing no fins at all. Once in the water, the Amphibian blades are flipped down into swimming position by simply kicking naturally in the water, and flipped back up by pushing back on the release levers before getting out. The fins are manufactured with the finest of materials. The blades are made from a combination of soft, durable thermoplastic elastomer (TPE) and a more ridged TPE. The soft TPE web is designed to increase propulsion and reduce the load required for sustained kicking and the more ridged TPE blade inlays increase coefficient of friction on blade. The Aqua-Hinge is a heavy duty hinge featuring 316-military grade anti-corrosive stainless steel springs. The fins come equipped with durable rubber fin straps that have an oversized thumb loop and squeeze-style" side-release buckles all for easy donning and doffing.Fins are available in multiple sizes and colors. Fins are proudly made in the USA.
