Received these in the color Sand today. They are warm and comfortable, though I am not sure there is any sign of the memory foam the product description mentioned. As everyone has said, they run SMALL! I ordered one size up and my toes touch the end of the slipper. But it doesn't hurt, and they should stretch just enough. The Sand slippers are on sale and I think they are worth the price. I don't think they would be worth full price. But for what I paid, they are good enough.

*Follow-up, October 2013:* It's been a year and they have held up just fine. They did stretch to be the right size. I wear them every day around the house except during the hottest part of summer. I got the "sand" color because it was on sale and I think it's really ugly -- but they are just slippers. Wish one of the darker colors had been on sale. Anyway, they have held up better than most of my previous pairs of slippers, and that's even though I have gone outside in them a few times. I got my money's worth.
