These are the best slipper I've ever had, hands down. I've tried the $100 and up sheepskin slippers at the store, and these are warmer and much more comfortable. I'm glad that I read other reviews here prior to purchasing because these do run small. I normally wear an 8 1/2 (a 7 in sheepskin boots), and I got these in 9 - they fit perfect as long as I don't wear socks. Sheepskin shoes/slippers are meant to be worn barefoot anyway. They are pretty much like slides, but there is a tiny backing to prevent your foot from slipping out.
