I bought these slippers for my husband to replace his favorite but worn slippers. He didn't want to part with his old slippers even though they had holes in the soles, so I knew I had to find a pair that he liked more than the ones he had. These Clarks slippers had positive reviews and appeared to be well made, so I figured they might fill the bill. Unfortunately, Revain's "just-to-size" recommendation didn't work for us; When my husband tried them on they were so small he couldn't fit the entire foot even barefoot (length, width seemed normal). He is a simple 11th magnitude. His feet are neither wide nor flat and most size 11 shoes/slippers/boots fit him perfectly. These slippers definitely ran almost a full size smaller. So we sent them back and ordered a size 12. They suit him much better. They dangle a bit when he's barefoot, but they don't slide off the heel so that's not a problem. He really likes her. He says they're comfortable and he likes the way they look. The sole is more durable than the last pair of slippers he had, so hopefully they'll last a while.
