Sporasub Revolution Fins

There is constant innovation being carried out on all kinds of scuba diving equipment, with better, faster, safer and cheaper gear being introduced in to the market with every passing year. One such company that has done some out-of-the-box thinking in fin design is Sporasub, a French company specializing in Spearfishing equipment, but has come out with a whole range of one-of-a-kind products with the Sporasub Revolution Fins being one of them.

Sporasub has created a unique foot pocket on the Revolution Fin. The foot pocket is actually a proper shoe and not a rubber pocket that you slip your foot in like in the case of an ordinary fin. In what may arguably be the most comfortable foot pocket available in the market today, the revolutionary idea of using an actual shoe integrated into a swim fin increases user comfort and takes away several of the problems people faced with using regular fins. A comfortable fitting foot pocket can mean no chaffing, and blisters, allowing for a better, less stressful dive.

The vamp of the shoe pocket is pre-molded and built of nylon with polyurethane covering with both materials waterproof and highly resistant to water. The padding used inside the shoe and internal sole are water-repellent, which eliminates water absorption, or water stagnation. There are three Velcro straps that secure the shoe to your foot to a custom fit and yet comfortable fit. The shoe sole is made from EMS Grivory thermoplastic (a leading provider of high-performance polyamides) with non-slip heels also made of polyurethane. The sole also has conveniently placed drain channels on the inside, which allow for emptying of water after use, in order to avoid water stagnation or build-up of mold in the shoe.

The Blade portion of the Revolution Fin is no less extraordinary than the foot pocket. The Revolution Blade is removable and replaceable made of high quality polypropylene. The 26º angle of the fin, with respect to the axis of the sole, creates a push that is equal during down-kick and up-kick, limiting the area of standstill where there is no thrust. The stiffness of these materials allows the diver to unload leg movement on the fins without wasting energy, giving you the highest level of performance.

There are also five stabilizers that have been inserted in the fin. The four lateral stabilizers, two on the upper part and two on the bottom, impede fin leeway during swimming. The central-upper stabilizer, moreover, while standing still during activities like spear fishing, keeps the fin slightly off the sea floor and thus limits any lifting of sediments. The fin is connected to the shoe pocket through the use of three stainless steel M5 metric screws which allows the blade to be detached from the shoe for replacement.
