I'm not a big "boot" person, and have been wearing sneakers non-stop. But when I ordered these boots based on the rave reviews, I could not believe the comfort and support they gave me right out of the box. I actually had to buy a second pair because I wear them every single day now and needed to let them air out between wearings! The men's boot in 6.5 fits perfectly. I normally wear a size 9 women's. The zipper adds a real "cool" factor. I show these off to the guys at work and they want a pair! Amazon's fast shipping and easy return policy make it simple to try on and exchange on size to get it exactly right. A winner.
