These fins are buoyant, helping lift your legs in the water to maintain proper body position and reduce effort, which is useful for swimmers of all skill levels.

They come in color-coded sizes to simplify finding the right fit, though swimmers with wider feet or those between sizes might prefer going a size up or using swim socks for extra comfort.

These fins provide a practical and effective option for swimmers wanting to improve technique and speed without sacrificing comfort or durability.
