Train the Tempo
When asked what coaches really want in a training fin, the resounding answer was to "provide muscle development, increase leg strength and improve body position at a tempo that promotes fast swimming”. Most fins today are designed to build strength or develop technique. Few allow the swimmer to “train the tempo” for building their championship kick.

A3 Performance Swift Kick Fins are designed to build strength in the lower body and improve body position while training. They also allow you to “train the tempo”. Made of super comfortable 100% Silicone, Swift Kick Fins are flexible and lightweight. As natural extensions of your feet these fins allow rapid movement, improving performance and overall power in a six beat kick. Now you can increase lower body strength, improve body position, and gain more endurance at a championship tempo with Swift Kick Fins from A3 Performance.
