MARES Avanti Quattro+ adjustable SCUBA diving fins white

The part of the fin where the foot is placed. It can be completely closed, like in full-foot fins, or open with an adjustable strap, like in adjustable fins.

The flat part of the fin that helps to generate the thrust. The longer and/or harder the blade, the more powerful the fin. The shorter and/or softer the blade, the less powerful the fin.

The soft longitudinal inserts control the deformation of the fin blades when kicking. The shape of this channel displaces more water, producing more thrust with the same effort.
