they look really comfy. i'd probablly wear them around the house with a cute boyshort panty and tank set. when i am at home my feet are always cold while the rest of me is warm so they would be a great temp. control. i don't think i'd wear them outside of the house. . .something to sock like about them to go out of the house in. cute idea though. . .
I can see the cozy appeal, but they do look like socks with soles attached...I somehow feel like you shouldn't go out further than the mailbox in them.
