Best Muclucs I've every owned....GREAT PRICE!
These things are so comfortable and warm. I sleep with them on because I like to have my feet out of the covers. Not too warm...just right. Great quality and fit with a non-slip leather-like sole. I'll keep ordering these ahead of time to make sure I'll always have a fresh pair when I wear them out. I wear them EVERY NIGHT and keep them on all morning. Life-changer! The BEST EVER!!

Great for indoor use.
Size: 10-11, Color: Cable Knit Navy
I bought a pair of these for myself about a year ago and there are plusses and minuses to them. They are comfortable and warm, without getting my feet sweaty or whatever. That's exactly what I wanted. On the minus side, mine ran far too small. I am a 10.5-11 shoe size and the 10-11 is about a half inch too short... my heels are sliding off the back. I am reordering a size 12-13 to try that one. In the take note column, the soles are NOT rubberized in any way. In fact they are like foam, and will absorb water! Also they do not provide cushioning against any kind of rough surface. I think they are perfect for strictly inside the apartment use, but they are not like moccasins or something that allow outdoor use. And I am ordering a 2nd pair after a year so I do like them.

Wonderful sock slippers
Size: 12-13, Color: Cable Knit Navy
These are wonderful sock slippers, They are very warm and well made. After reading reviews, I decided to order one size larger (10 to 11) and they are really comfortable big. However, I'm glad I did because they a lot easier to put on and take off. Highly recommended.
