Got these to slip on real quick to take the dog out since the ground has been so mushy. I don't even have to use my hands I can literally just step my foot in, I'm super lazy so to me that's awesome. I have large calves (16 in) so I was a little worried they'd be tight but they're short enough to not matter at all, and Id even be able to wear thick socks or even leg warmers with them. I wear a 7, sometimes 7.5 and I got a 7 and they fit perfectly. Just gotta wear tall socks cause I mean they are rubber so ankle socks get pulled down.
