I've been wanting to try Croc's for a while, and decided to replace my worn out Dearfoam slippers with the Blitzens. I read all the reviews here and still decided to order my true size, 11W/9M. Honestly, I couldn't stand for these to be any smaller, and wearing socks with them is definitely out, but they are lined for a reason, so it's really not a problem for me. They are very comfortable, in fact, I haven't taken them off since they arrived this afternoon. They also don't slip and slide on my hardwood floors. I typically wear Birkenstock clogs in the winter so I'm used to a shoe with a large toebox, but these look almost abnormally large. I don't think they will score any points for attractiveness, but that isn't really what I look for in a shoe anyway... If I were to purchase another color, I would probably size up so I can wear socks with them when I leave the house. The liner is nice and soft, but will slip out when you remove your feet. It's easy enough to push it back in, though. I don't intend to try to remove it for washing unless they get really dirty or start to smell. In all, I'm very pleased with this shoe, and will probably try other Croc's styles in the future.
