"These are comfortable and run true to size. I'm normally a 6.5-7 and like a little room in my boots so the 7 fit perfect--snug but comfy with a warm pair of socks and normal with an average thinner sock or tights.
The shaft of the boots fit me perfectly, which rarely happens because I have very small calves, so if you need a wider boot shaft I wouldn't recommend these. At the widest, my calves are about 13.5 in. and they fit me well. The boots themselves measure 15in around the outside of the shaft."
