My wife loves these. They are a little tight in the beginning but they break in just nice. She wore her first pair all thru winter and kept her feet nice and toasty.
I ordered twice, both pairs were larger size than I normally wear, but they were so stuffed with warm padding that they ended up being too short and narrow. suggest 2 sizes larger than normal. Otherwise, lovely, exceptionally warm slipper that would appear to do well outdoors, as well.
