I've sent back 2 pairs of these slippers. The first pair I ordered  were 1/2 size bigger then I usually order. I did this because some of the reviews mention that theirs were a little to small. The pair that arrived had the correct size cast into the sole of the slipper. The fit was so tight that when I finally got it on one foot the top of the slipper was all wrinkled up and my toes were cramed over the front of the slipper. I sent them back to exchange them for a bigger size and as I stated earlier the size I ordered was on the sole but when I tried them on they didn't seem to be any bigger then the first pair. I sent them back for a refund and bought a pair locally.
