Review on Long Floating Fins For Swimming And Snorkeling By FINIS – Use Size Chart For Accurate Sizing by Eric Longoria

Fins are good quality and float as stated in the description. Bought them for my son who is tall with big feet and wears a solid 3.5. I was a little confused about the sizes offered and descriptions in the size chart. I also noted many of the customer questions are confusion around the sizes offered. I purchased the size SM 3-5 just as the size chart suggested. However, like many other posts here, they were too small. My son's toes stuck out of the front about a half an inch. It wasn't bad, but I was hoping they would be a little big so he would have room to grow! Ended up giving them to his little sister who wears a size 2.5 with very narrow feet (his are wide) and they fit her. She can donate her cheap plastic 'mermaid' fins to another child. I am going to order the next size up for my son and hope they fit him properly. If you purchase, they are really nice fins but I would definitely order one size larger.
