They  looked cute and warm (my feet are almost always cold), but they are VERY hard to get on.  They have no give, and no zipper or anything that would make the process easier.  I even bought them a size too big so that I could wear socks with them, but I'd never actually get them on my feet if they weren't bare.  Also, the seam started to come undone on the back of the right bootie.  I had Acorn slippers before and they were durable and warm.  I don't know if the quality has started to slip or if these were just a poor design.  When I am wearing them they are comfortable and my feet aren't freezing.  That's the best I can say.
