This was a great buy for me.  I ordered up 1/2 size and the fit is fine for me.  My feet a slightly more narrow than a normal foot,  but I usually don't have to buy narrow.  I really like how easy it was to put it on and take it off. I shoveled the driveway with these on and my feet were toasty.  I just bought a pair for my mother-in-law as a gift.
