During the kick cycle the structure of traditional fins creates a limit to the angle of which the blade can flex. This limit allows only a small part of the fin blade to push water in the direction of the kick, while the remaining part pushes the water in the opposite direction, reducing the diver's forward thrust. The O.P.B. system patented by Mares causes the blade to flex at an optimal angle during both the upward and downward strokes. This optimal angle allows the majority of the blade to push a larger volume of water in the proper direction and greatly increase efficiency. All of the diver's kicking effort translates into positive thrust. Traditional fins produce lower levels of thrust at different points in the kicking cycle with substantial differences between the maximum and minimum values. The O.P.B. system produces optimal thrust throughout every phase of the kicking cycle, which minimizes fatigue and produces a more fluid movement through the water.

 

Latest development in Channel Thrust is the Superchannel. The blade is designed with a large flexible central Superchannel propelling water-flow more efficiently down the fin blade instead of letting it spill over the sides for optimal performance and minimal diver effort.

 

The open heel foot pocket is designed to accommodate dive boots with a sole, and to offer excellent adherence between the boot and the foot pocket in order to transfer all the force exerted by the leg to the blade, without sacrificing yield yet still ensuring superior comfort. The lower section of the foot pocket is longer, in order to better transfer power to the blade and minimize the risk of cramping. In addition, the inside of the foot-pocket features internal ribbing to improve fit and stiffen the sole.

ABS Plus Buckle: Unique and patented design. It only takes one quick movement to easily open or close the buckle, even when wearing thick neoprene gloves. The double button release prevents the buckle from accidentally opening. The most user friendly in the market.
