Fit - runs a bit big. I wear an 8 in flats and 8.5 in boots and sneakers. I bought these in the 8 and they were big. i could've worn the 7's I think.

Quality - seemed good at first. I wore them one time (at a zipline park where we walked up a lot of stairs, and zip-lined into the water) and the inner lining came unglued after about an hour! It was very uncomfortable to wear these all day with the bunching up of the liner. As much as I tried to put it back in place, it kept bunching up again.

Same thing happened to my fiance (he purchased the men's version).

We both threw them out at the end of the day :(
