Womens Black Aerosoles Slippers Size 8.5 Size 9 Size 9.5

Quilted black fur lined slippers Worn about 3 times (just bought at work when feet hurt) They seem to run small as I wear an 8 and these are marked 9 and a 1/2 to 10 and a 1/2 XL, but they fit me so the best size they would fit would probably be 8 1/2 to 9 1/2. The inside footbed measures 10.5 inches & my size 8 shoes measure 10 inches.
