My wife gave them to me for Christmas, and I put them on that morning. They were a little stiff at first, and the heal was a little too firm. But by mid-day they were feeling great, the stiffness was gone and the heal softened up real nice, very comfortable. I'm real picky about slippers and I would recommend these to anyone. My wife ordered a large which according to the manufactures chart would be an 11-12, I wear a 10 1/2, and they fit perfectly, so take that into consideration.
