This shoe is amazing. So comfy, very warm despite only a fleece footbed and windbreaker-like rest of shoe. I will be living in these and ordering more colors. I have a messed up ankle from a car accident, most shoes cause pain, but not these, and GREAT traction! As far as sizing goes, 1/2 sizes would be brilliant...otherwise I'd say true to size. I am a women's 9 1/2, got a 10 to be safe. They are a little roomy as they are unisex. Not narrow by any means. My nxt pair will be a women's 9 just because I will want a pair to wear sock-less.
Ordered on a sat, rcvd the following Sat. Altrec did not disappoint.
