Tusa X-Pert Zoom Open Heel Split Fins (SF-8) Overview
When using the standard, flat fin, propulsion is inhibited solely by fault of design. When the leg is completely extended, there remains an angle of 27 degrees between the heel of the foot and the calf of the leg. This 27-degree angle causes 10% of the propulsion that is produced by the kicking motion to be lost. Because the fin is angled below the body, during the kick phase, the body is pushed up and forward, instead of straight ahead. With a normal flat fin, 10% of the diver exertion to propel him forward is lost by battling this upward force. With the TUSA X-PERTZOOM FIN, that 27-degree angle has been incorporated into the fin. This means that when the leg is fully extended, even though the angle exists between the foot and calf, the fin ends up parallel to the leg. This means that 100% of the energy expended during the kicking phase is directed toward the propulsion of the diver.
