If your wanting a boot for warmth, this isn't it. This is strictly a fashion boot which I would recommend for transition between fall and winter, or winter into spring. I wear a 7.5 but have a high instep so I went with a whole size up. I wear it comfortably with no slip in the footbed. Its a pull on boot no zipper. If you have large legs be prepared to rock this boot folded over and not all the way up. My calves are 15" and my thighs are 191/2. I barely can wear them all the way up. These boots would be awesome with a little goring and a fur lined foot bed. If you want to wear them waterproof them for sure.
