Comfy, but my feet slide around and these are an 8 (I wear usually an 8.5-9.5). The area where the Velcro is gets pushed under and so the edge of the Velcro digs into my skin. I've adjusted the strap so it's looser, but my feet slide around even more. I had high hopes for these. I need slippers with arch supports, but I'll have to find a different company, or ones without Velcro.
