## Questions & Answers

**Q: Can this monofin fit on the mermail tails?**
A: the monofin is the mermaid tail.

**Q: Are these made of hard plastic? I'm looking for a pliable rubber type fin.**
A: Fin is slightly flexible plastic. Only flexible bit is the top part of the foot bit.

**Q: My daughter wears a 12.5T would this fit her?**
A: Probably. However we purchased these for our 9 year old and they were pretty terrible. They don't stay on at all. She tried wearing water shoes with them and that didn't  help. And then they broke. They were so cute but so disappointing. :(

**Q: what size foot does this fit?  Are these toddler or childs size?**
A: Bought for a 6 year old birthday who was swimming but not strongly.  She wore a 12 shoe I believe and they were big on her.  This year at 7 and a 13 they fit much better (but still plenty of room to grow) and she was able work them well and they are quite a work out.  I do watch her carefully when she is using them and make her swim around the perimeter just in case her feet don't slip out.  She thinks they are fun to use, but they definitely hinder swimming not aid it like separated foot fins, you have to do the mermaid worm dance to move through the water.  I wear a 6 and was able to use them also.
