Question: what size are these?
Document: my daughter and i loved this item. i found that the product was flexible and solid is perfect for my daughter. it was the right size and it was perfect.
My daughter loves this fin - she uses it regularly at our local pool. She is enjoying being a mermaid. The fit was great. She wears a size 6 womens and it fit fine.
My girl was thrilled with this. Possibly her favorite Christmas gift! High quality, good fit despite her larger foot size at age 14. Thanks Finis!
So, not only is this product being sold claiming to fit sizes beyond the size range it will safely fit, but it also claims to be usable by that size range in a very hazardous environment. Buyer beware.
My Daughters are already fighting over this. It does have an adjustable back. Heed the size though, it has a wedge-type insert  to fit down to maybe size 3, but I don't think will fit my own size 9.
Children's size however I bought it for myself and am a Women's size 7 and it fits perfectly thanks to the adjustable straps. Very sturdy fin that is very fun to use. Would recommend it to anyone!
The Wave was really good quality and good weight, but the size description stated that it would be able to fit a men's size 9, women's size 8. It fit neither. Had to exchange for the rapid.
I love it. This was my first monofin. I have a size 8 foot a little on the wide side so I was between this and the rapid.... glad I chose this because it fits just fine and works wonderfully. Would not fit a size 9 though!
I wear a size 8.5 in women's and this fit just fine. I had to adjust the strap a bit. Only issue was the small plastic bar the clip goes on between the feet section of the monofin broke. Other than that, it gives you a break workout and people definitely notice you when you're swimming!
I ordered this fin and the FINIS Yellow Foil Monofin (Small). Am keeping both, as they both have their uses. Also, when my finless friends come over, they can try one out, too.Best part is the strap is easy to adjust. It fit a man's size 10 foot well, and didn't hurt my feet wearing just socks.
Answer: no
