Mermaid Monofin - Swim Fin for Kids - Swimming Flipper with Comfortable Foot Pockets - Snorkel & Water Accessory Made w/ Dive-Grade Neoprene

This is AMAZING. Made my kids day!!! Will say that we had to size up from the kid version to the adult. She’s a size 4.5 ish. But we had a hard time getting the kid size on so switched to the adult and it’s great. Seems durable and honestly, she likes it so much and it’s so neat we’d buy another even if this one does wear out. Bought a tail cover from another brand on Amazon that fits over this perfectly, so in the water she looks great! Had her practice getting it off in the water and she was able to easily and very quickly, which made me happy.

Amazing! My little one LOVES this tail. We had to buy and return a couple of duds before we found this one. Great quality. Fits her feet perfectly and isn’t slipping or popping off.

I wasn't sure I got the correct product and had to measure it. It looked small but it measured the correct width for the adult size. This fin went to a pool party and got stress-tested by me and three young boys. I think my feet were the smallest. The boy with size 9s had some difficulty getting his heels in. He gave up but was still able to use it even though it wasn't correctly worn. The ankle openings were very tight. It doesn't make any difference what size your feet are. If you can get your feet into those ankle openings there is nothing else there to hold it on. Too tight and it can't be removed in a hurry. Keep that in mind. He had it so the openings were around his feet with his heels out and swam with it. He had the same fight the rest of us did getting it back off. It's a bit of a learning curve, but if you can tread water you can do it. It's easier to remove if you can stand in the shallow end. The cover of the fin is neoprene and just a bit thicker than swimsuit material. It held up well for the party and fit me fine after all my poolmates had a turn with it. The tips of the fin rubbed the pool walls and bottom and showed holes, not just fuzz, when we got out. Even I couldn't avoid rubbing it against the pool walls and bottom. They didn't affect its use, but could eventually open enough to no longer hold the plastic fin inside. If you sew, you could repair that with swimsuit material patches. Over all, it was a fun pool toy and I'm glad I bought it. I left it with the boys since they swim more often than I do. We all had fun swimming like fish.

Great build quality and fin fun in general has never yet sent me a bad product, though the reason it’s at four stars and not five is that though the user of the fin is well within the age range advertised, it is very hard for them to slip their feet in. I also have an adult monofin in the largest size available and I has the same issue. Though our feet aren’t exactly small for our age, my feet are within the sizes it says it works with, and it’s hard to get on quickly. However, at least once it is on it is comfy around the ankles. It works better if you have smaller feet, but overall good quality and worth the price.

I use this all the time in my pool. Fits PERFECTLY!! I’m a size 8 in shoes and worried it would be too small but it isn’t and I’m so glad! It’s comfortable and the material never scrapes on my pool deck. Definitely worth the cost! I’m obsessed!

So good. Works well in the pool my daughter loves it

The holes are a little too small and hurts to put on. Wish it came in another size but other than that it was amazing I'm able to wear it and I can't wait to use it.

This would be 10 stars if they reinforced the sides of the fin because it is super fun, flexible, soft, well fitting and nice with the exception that both sides ripped within the first 35 minutes of use! My child was heartbroken because it is such a fun monofin. I cannot recommend this product as it is, but if they reinforce the material on the sides and corners, I would be happy to!
