Speedo Fastskin KickFin

Train smarter with the Fastskin Kick fins. The Fastskin Kick fins were developed using insights from world-class athletes, sports scientists, and global hydrodynamics experts from Team Speedo. They are our best-fitting fins yet and feature a unique foot pocket designed with 3D foot scan data. The short blade with double rail captures more water during the kick and provides increased propulsion. The fins are 40% lighter than our next competitor for faster turns.

Using 3D scans of foot shapes, Speedo has developed fins with an optimal fit and superior comfort. The larger foot contact area also optimizes power transfer, allowing you to swim longer and faster without discomfort.

The short blade with double rail displaces more water during the kick and optimizes the energy transfer from your kick to the water for faster propulsion compared to a flat fin.

The dual-material construction makes the fins 4% lighter for quicker turns and less soreness in the hip flexors. The profiled sole provides better grip during turns or jumps from the starting block.
