FINIS Luna Mermaid Fin

Calling all members of the Ariel swim squad... get your mermaid on with the Luna Fin and swim better to boot. The Mystic Melon fin is for junior mermaids, shoe size US 11-3, and the emerald for experienced mermaids, shoe size 4-9.

Dive into an enchanting underwater adventure with the Luna mermaid swim fin. Luna instantly transforms any swimmer into a real mermaid and allows users to glide through the water with the same graceful movements. Inspired by mermaid legends and the vibrant colours of the sea, the Luna monofin also teaches a balanced underwater dolphin kick.

Crescent shape and rippled edges allows swimmers to glide through the water like a real mermaid.  In luminous colours inspired by the sea, the translucent silicone produces a magical glow in the sun. This monofin teaches a balanced dolphin kick and builds leg strength. It has an adjustable strap and fits a variety of shoe sizes.

Junior mermaids are best suited to the S which is for Euro sizes 28-35.  Intermediate mermaids will like the M which is for Euro sizes 36-42.

Caution: Not intended for novice swimmers— use with adult supervision

Feedback from mermaid field trials:

"Real mermaids only! :-). This monofin is AMAZING!! Gorgeous shape, great fit, and feels so real! Nicer to swim in than the hard plastic tails (although those are great for kids who are still growing).  If you're a SERIOUS mermaid, you HAVE to have this!!" - NICOLE

"It’s is very comfortable and has a nice mermaid aesthetic. I would definitely buy this product again but I have no need to as my fin is holding up so well. I recommend this product for open water swimming." - SONYA
