These are comfortable, soft, and warm.  Totally awesome!  These slippers are perfect for around the house, running to the mailbox at the end of the driveway, sweeping off the porch, taking the trash out, etc.  The arch support in them works very well and the memory foam is like walking on a cloud.  Your foot sinks in with every step.  These slippers are some of the most comfortable I've ever had.  I actually wear a 7 1/2 which is a medium, but in the winter I like to wear thick fuzzy socks, so I ordered a large and they are working out perfectly.  I would definitely recommend these to a friend!
