When I first put these on, they felt a bit tight, but they have stretched out to fit fine now. They are super warm and comfortable, and when I don't have them on, I'm always looking for them now. The only downside is the material inside seems to fall out a little at a time. I definitely recommend these to anyone looking for some warm comfortable slippers. Also, I only use them inside. I'm not sure if some people take them out, but I don't.
