I wear a 9, ordered 8.5, fits good. I don't recommend wearing them for long periods, but maybe I just need to break them in, the first time I wore them I took them to a harvest festival, so lots of walking, I have high arches & really wide feet tho. I have big calfs, it's nice these zipped right up without a struggle. They look really good on, as far as comfort, as long as I'm not standing & walking for too long, just sit & look pretty.See full review
