They're VERY cute, and they fit nicely, but it feels like I'm walking on a stuffed animal because the soles are so poorly positioned (size 9/10). They ARE warm.

I'm personally just keeping them under my desk, so if my feet get cold I can slip into them. They're just not comfortable to move around in, so I'll use my other slippers (which are super comfy and the best, but not Hello Kitty ;)) mostly instead.

If you just want cute, warm Hello Kitty! slippers, then this will be awesome. If you want to walk around in them...not so much.
