## Description

desertcart.com : Sun Tails Mermaid Monofin (Turquoise, Nunui - Teen/Adult Size) : Sports & Outdoors

Review: Nice and comfortable. - Very nice. Daughter is loving them and the neoprene boot is comfortable.
Review: Fun for swimming! Tight for wide feet - Really like the rigidity of the fin. It’s not hard like glass but just ever so slightly flexible. One can really propel oneself through the water after perfecting one’s “flipper technique.” The sock part is fraying after just a few days of swimming, although neoprene doesn’t hem like other fabrics. We went with the Keiki size for my tween (sz 6 shoe US) but the sock is difficult to put on once her feet are wet, perhaps due to wide feet and being on the upper end of the size scale. We have no problem cinching the fin into the sock with the Velcro and the straps work quite well for us. Ideally there would be a medium sock offered with the Keiki fin. But I’ll exchange the current one under warranty when it rips completely.

### ⭐⭐⭐⭐⭐ Fins
*by A***L on May 6, 2025*

Loved them so much!! I do wish I had gotten a smaller size, I wear a woman’s 7 and they are a bit big. The adult size is what I ordered. I should have gotten a child size. Overall they were great and very fast shipping. Have used them in the pool and no rips or tear’s.
