There are two styles of Monofins available, competitive and recreational. If you're just looking to swim like a dolphin, then select a recreational fin that corresponds to your shoe size. Recreational Monofins are not sufficient as a training tool for competitive swimmers.
Fun, safe and easy to use in any aquatic environment, Recreational Monofins require both feet to kick simultaneously in the motion of a dolphin kick. The result is fast and fun propulsion through the water.
The Wave Monofin has a soft Monofin blade and is adjustable to fit children's shoes sizes (1-7). For ages 5 and older. Blade measures 21" x 18".
