Zoggs Ultra Fins Swim Training Blue

The Zoggs Ultra Blue swim fins with short, small fin surface and Dual Density weight have a soft and pliable foot mount, while the fin is largely solid and thus provides optimal propulsion. The Ultra Blue swim fins are lightweights that allow a well-balanced and naturally rhythmic foot and leg technique. The low weight also reduces muscle overload, which in some cases can lead to cramping even after swimming.
