Scuba Diving Fins Cressi Frog Adjust

The blade is born directly from the upper part of the foot pocket, solidly joining the fin to the foot and transmitting all the effort generated by flapping without loss of energy through soft areas.

This format allows the water to be channeled from the same ankle to the final edge of the blade, unlike traditional models, in which the foot pocket has no contribution to advance.

Apart from improving the directionality of the flapping, this design provides a performance between 10% and 15% higher than what would correspond to the fin due to its blade surface.
