Beautiful soft suede, more brown than olive green. I was hoping to be able to slip these on even though I knew there was a short side zipper. They are fitted across the instep and ankle and slip-on is not possible. The lining is very thick and cozy warm and that also made them a bit tighter than I expected. I usually wear an 8.5 US. I really love these boots, they seem like they would break in well, but alas, not exactly what I am looking for.
