Mares Fins Avanti Excel Fins | have a closed, anatomical foot pocket | whale tail design allows the power of the fin to be transmitted optimally | channel shape displaces more water, creating more thrust with the same effort | Tri-material fin with Channel Thrust technology

The Mares Avanti Excel Fins are designed for top performance in all diving situations. They feature a Super Channel Thrust system that significantly increases the amount of channeled water, creating more propulsion compared to fins of similar size. The elastic OPB system ensures that the fin blade bends at an optimal angle during the upward and downward movement, increasing the efficiency of the fin stroke. The 'whale tail' part of the foot improves power transmission and sensitivity when swimming.
