I have a black 7.5 Med Aerosole suede boot (of a different style) that fits me absolutely perfectly. I could run comfortably in my black pair, so I was excited to see an option in brown. Anyway, initially this pair was a little tight, and I had to break them in. This is unusual for Aerosoles, so I was disappointed they didn't fit great right away. The good news is that they fit great after a break-in period.
