    The strap that secures the heel into the fin it is poorly designed and the fin is too rigid— as soon as the kid kicks to swim, the strap comes off and the fin falls off. I would return it if SO’s process wasn’t such a PITA for people who don’t create an account when they buy.

    1 Review Stars By Preachermom

    My daughter has been wanting a monofin so she can swim like a mermaid for months on end.....too bad this didn't help!  She can get (mabey) three strokes out before the fin slips off.

    I have small feet and thought I would give it a try.  I wanted to see if it was the product or my daudghter needing to learn to use the flipper.

    I couldn't keep it on either.

    The single strap across the back would be better if it were two straps, holding each foot in place.

  • 7/10/2017 Fantastic, but

    3 Review Stars By ATJD

    These fins looks and works great if you have a concrete pool or in a pond/creek.  The  first problem is that the fins are very sharp and if you have a soft pool liner, they WILL puncture it.  It's not really a question of how careful you are, the movement of the fin is such that they scrape along the sides and bottom of the pool and puncture it.  The second problem is the size.  The ad says they fit female sizes 2-7 and that is simply untrue.  I'm assuming that is children's sizes because this is marketed for kids 6yrs+.  If you have a size 4 or greater or wide feet, do not buy these fins.

    5 Review Stars By Heather R.

    My daughter is 10 and obsessed with mermaids.  I got the Finis Mermaid monofin for her birthday.  While its been unseasonably cold, so she hasn't been in the pool yet, she is soooo excited!  She will wear it in the car, with her fin on the dashboard... Or lay in the floor with her "tail" behind her up in the air.  I haven't seen her get that excited in a long time.  It's a starter fin, but seems to be made very well.  We wish the box it was delivered in had been smaller since they used a gigantic shipping box... But it arrived when promised and its wonderful.

  • 9/9/2016 Make believe fun

    5 Review Stars By Alice

    Our fin has lasted 2 summers already--and, Houston's summers are over 4 months of the year!  The soft and slightly elastic ankle strap stay on small feet, after a few minutes of getting used to.  This fin gets passed around kiddos friends.  They'll wear mermaid swim tails over them too. Economical and beautifully shaped.

    Compared to the Finis monoswim fins, these make you swim harder and the fins slide off more easily.

  • 8/30/2013 Loved the Mermaid Swim Fin

    4 Review Stars By Helen M.

    Granddaughter age 11 has these comments. She loves it and has made a mermaid fin to cover her legs with mono fin inside. She wears it when she goes swimming and is an excellent swimmer. These are her suggestions. Make fin wider where feet fit~Make buckle flatter and out of firmer material~Make barrier between feet a little taller and extend a little further back~Plastic is brittle breaks easily~ Make back strap a little longer so older kids can wear it~Make fin a little larger such as 1" wider and 1" longer.  Make same style in an X-Large.
