The quality of the slippers are fine, but they seem to run small. My dad wears size 10 1/2 shoes, so I got the XL slippers. They were too tight across the top of the foot for my father to be able to slip into the right one while wearing socks. At 87 years of age, he shouldn't have to struggle with putting on slippers. They may stretch out, but I didn't want to wait, so I'm still looking. I passed them on to my brother, who wears the same size, and he likes them.
