I usually wear an average size 10.5. Bought at 11 and 12. 11 is too tight. 12 are narrow in width and just long enough for my foot to stand on the sole. I wear socks with mine so that doesn't help. I use every pair (3x) I've bought even though they are small. I have no problems with them in the house. If I were to buy them for external use I would honestly go 3 sizes up. A size 12 is about as small as I want for slippers and as I said I wear a size 10.5. For the price they are great. They seem to be holding up well when I toss them in the washing machine or shower occasionally. They don't absorb water like my adidas so do very well when wet. Overall a good buy if you buy 2 or 3 more of these. The quality is excellent.
