not the best slippers I have had. Loved Rockports, but they are nice.
but anyway, they are warm and comfy, but I wear a 10 1/2 shoe and I bought a 9-10.  they were tight at first, but now after a few months they are big on my sons feet. he wears a 11. they feel like 11 1/2 or 12.
I think if they didn't grow so much I would give them a 4 star, maybe even a 5.
The sole is a little flimsy too.
