These slippers could be comfortable if they were sized correctly. Because shoes/slippers are not made to proper size in the industry, ever since manufacturing went overseas long ago, I normally wear anything from size 10.5 to 12. So I bought size 13 for this slipper thinking I was buying something a little bigger than I'd need and it was still way too small. Unbelievable! Narrow fit and the part that comes over the top of the foot is too long, coming too close to where the foot and leg connect.
