Description: The ACTION training flippers from AQUA SPEED are an excellent option for those training for swimming. The comfortable, flexible wellingtons fit perfectly on the bare foot. Very easy to put on and take off thanks to the handles on the wellingtons. The ACTION fin has rubberised side reinforcements, extending its life and contributing to its stability, as well as a hole to reduce the load on the fin blade during acceleration. The ACTION fin's appropriately shaped centre and its blade made of elastic material create a tunnel that directs the flow of water along the blade, increasing thrust and swimming speed. The stiffened sole prevents muscle cramps and the rubberised underside of the fin protects against slipping on wet surfaces. With the ACTION fins you will increase your speed in the water, strengthen your leg muscles and their flexibility, and improve your swimming technique and your position in the water.
