I normally wear sneakers 6 1/2-7, there was no size 6 1/2 so I thought I’d try the six, thinking they’d probably have to go back. When they came, they looked small, since there are so light and stretchy. I tried them on, kind of fit like a glove, for me, they felt really good, snug but kot binding, Felt like my own foot with a protection on the bottom my toes weren’t crunched or hurt hurt snug but felt good.Wore them for paddle boarding,Nice lil grip or traction, on the paddleboard without feeling clunky, thick and bully sliding around felt ver natural to me. I was in the water, then covered in sand, also my friend bounced around on the hot sand i chuckled is it hot? Since I didn’t feel no heat on feet ?when we got to the pavement i stomped sand off and removed, these lil shoes, and my feet hardly had any sand on them. Im like Wow I really liked these water shoes! This wknd i will be using in sons pool that always scrapes my toe on bottom?definitely recommend and good price
