Very comfortable. I am a size 8 1/2 and purchased the same shoe in gold and in a slightly different style. While the gold shoe fit perfectly, this shoe is a bit wide and slightly too large, but it still stays on my foot, so far.  I'll have to wear it longer to really tell and hope it doesn't stretch.  THe buckle does jingle a bit on just one of the shoes and that is somewhat annoying. All that being said, the Aerosole Stitch n Turn is a very comfortable shoe!
