## Customer Reviews

### ⭐⭐⭐⭐⭐ Very good fin my daughter loved it!
*by R***N on January 10, 2026*

Definitely would buy again!

### ⭐⭐⭐⭐⭐ Looks great!
*by E***N on March 8, 2026*

Perfect fit!

### ⭐⭐⭐⭐ Good product but insufficient ankle support
*by C***D on November 1, 2024*

I like how big and strong the tail / fin is. The detachable neoprene foot part holds to the hard fin with 3 Velcro straps and can be dried separately. On using it I noticed that ankle support was missing, and a lot of leg movement did not transfer to the fin beating, but instead overstrained my ankles. Until I find a way to secure the fin to my ankles, I won't be able to get the benefits of monofin swimming for my back and abdomen. I'm a bit sad but hopeful that I can find a system.
