When I took the shoes out of the box, I thought, "Well these will never fit"!  They looked small.  I was surprised how easily they slipped on and they were not too small.  They felt so snugly warm.  Good support.  Unfortunately, after wearing them for several minutes they started to rub my ankle, just to the inside of the Achilles tendon.  I was greatly disappointed.  I sent them back but still giving them a 5 star rating because I am a female, buying a men's shoe for the width of the toe box.
