Fin Fun Mermaid Monofin, Swim Fin for Kids and Adults

Fantastic. Easy to use. Monofin is well made. It arrived very fast. It fit perfectly. And swimming with it is ultra fun. Definitely worth the purchase price. 🤩

I love how comfortable this monofin is. It's got as much room as you want for wiggling your feet and stretching out your toes, but it still holds onto your feet and works great to make you swim faster. My boyfriend (pictured) prefers a firmer fin - he thinks this one is too floppy - and he prefers the linden monofin with its individual foot holders and straps, but I love how easy and comfortable this one is to wear and use. It's just a flat fin and your feet are held in by a neoprene sock top that holds to your ankles, but once your feet are inside, they are just comfortably held to the fin by a fitted sheet of neoprene that gives you as much room as you want for any size and shape of feet. Swimming in it was easier than I expected - I zoomed around the pool. I haven't used it with the mermaid costume yet - it turns out that most public pools forbid mermaiding - but the fin itself is great and much more comfortable to me than the ones that have individual foot buckling stations. If you're more used to other more-restrictive swimming flippers, you might prefer the linden monofin, but if you hate feeling constricted, this fin is a real joy.

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.

I love it I enjoyed using it for the first time the other day when I got it. I did run into a few issues at my local gym using it they were a little cautious about my safety. so you might run into that when going to local pools the lifeguards me to tell you that you can't use it but I was able to get clearance from the manager and they said since I'm an adult and Avid swimmer it should be fine. The sleeve is removable there is a opening at the bottom where you can take it out and dry it. Putting your feet inside if you have big feet like I do I'm a size 11 wide flat foot it may be a little difficult getting in and out of it. So I'm going to modify and put Velcro on the back to make sure I can get out safely. Other than that it's a pretty good deal. Kind of wish it was a bit heavier on the tip of the fins so I could do tight turns but a few modifications should fix it.

Looks to be good quality. Fit my daughter and my niece very well. I was worried it may not fit in the mermaid tail I bought, but it actually fit perfectly. I have so far only used it for pictures, so I cannot say how it is for swimming.

So I bought the mermaid fin (fabric) without this and only after my child tried it on did, she realize she needed this attachment. Watching my 13th year old daughter and her friend try to get into the fabric with this one was worth every penny. It is a bit expensive to buy both pieces, but the girls enjoyed it, and we got a good laugh out of it. Once the tail was on and assembled completely the girls had fun. It fits well and the girls were able to swim. When they were ready to exit the pool, I about died laughing while they tried to de-fin themselves. I highly recommend if you need a good laugh.

The media could not be loaded. I was beyond worried they wouldnt fit my feet (size 11), but its the perfect size! you catch serious speed with this! Easy to use when you only use your core muscles and not your legs :) great for the price!

A very fun toy that works well in the water. Unfortunately the fin tips rip easily. After 3 uses the fabric is significantly torn. The tips should be reinforced with some kind of rubber coating. This item might last longer if it’s used in a pool only, rather than river/lake.
