Sharks Wear Mermaid mono-fin for children with adjustable strap. (Pink)

The strap comes loose occasionally but my daughter wore hers ALL DAY in the pool, and had to readjust the strap maybe six times. She loves the fin, got her rather large feet (ladies size 6) in the fin easily and had no rubbing issues or problems. I would highly recommend this fun monofin for any child capable of swimming. Great fun!

Strap slips just like people said. Cute for a short amount of time but you need to get smart with your design to keep them on and hope you can get out of them.

My niece who is 9 loved these fins, they are sturdy and look nice on. However, they are better suited for a child that can swim really well underwater.

I purchased these for my 5 and 6 year old girls. Even on the tightest settings, they can not keep the fin on in the water. Wondering if it was too big for them, I tried it myself, and the strap just slips right off. Very disappointed.

My 9 year old loved it. Fits well and strap will adjust to fit her feet as she grows (currently wears US Big Kid 2)

It was great I got new mermaid tail with it because the first one ripped

My granddaughter loves it. Kelly Mermaid got her tail :)

Kids love it! Takes some practice and skill.
