our foot is on the small size we are a size 1 and the velcro is sinched all the way up and they want to fall off occasionally when they stay on it is ok

my 3 yo wears his "water shoes" and then flippers work just fine. He now swims independently. Soft so he walks on them no problem.

velcro didn't stay together.  I will return these

Thought  it would be great to have fins my kids could grow with howeverthey were already too small for my nine year old and the velcro is not strong enough to work for my 7 year old.  Sent both pairs back.

We like the fact that they are sized and adjustable.  Hopefully when the gradkids have outgrown these there will be a larger and adjustable size available.
