When I purchased these, the sizes showed L as 9-10.5 (or something similar).  Now that L shows 7-8.5 it is more accurate.  My feet are 8.5 and these uncomfortably squeeze my feet with socks on.  I can wear them barefoot, but just barely (will have to keep my nails trimmed).  My assessment would be not to get these if your shoe size is larger than 8.  Also if you are looking for slippers to slip on hands-free, you will not find that here.
