I wear a woman's 9 wide, and I have plantar fasciitis.  It's really hard to find supportive slippers in that size, so I took a chance and ordered these in a mens size 8, after reading other reviews that they tend to run small (otherwise I would have tried a size 7).  From the first moment of wearing these, I have been so pleased.  They fit like a glove and are very warm, and they support my foot bed so much better than any other slippers I've tried.  I wear them nonstop when I'm home. When the weather gets warmer, I'm going to be looking for more Sorel slippers, without the warm lining.
