Description:

The new Mares X-Stream fins get their name from the X-Stream Comfort and X-Ceptional Efficiency of this unique fin design. Mares X-Stream fins feature a perforated foot pocket, which allows water to drain from the space between your boot and the foot pocket, eliminating excess drag. Mares X-Stream fins also feature Mares patented OPB system, which causes the blade to flex at an optimal angle during both the upward and downward strokes, increasing the efficiency of the divers kick, plus the straps feature ABS Plus (Adjustable Binding System) for one step quick and easy opening or closing.
