The result is greater power with the same amount of effort.The blades are designed with a large flexible central superchannel that propels water flow more efficiently down the fin blade (instead of letting it spill over the sides) for optimal performance and minimal diver effort. The thermoplastic rubber/trecralene footbed allows for a comfortable fit, eliminating the need for protection against blisters. Upper and lower stabilizers are vertical ribs that anchor the blade through the kick cy
