My 8-year-old son starting complaining about his "baby" slippers (rocket ships) even though they still fit. Seeing him run around barefoot in the house in the winter sent me searching for a slipper his size which would be "manly" enough for his tastes.

This shoe is sturdy, warm, and comfortable---but looks more like a grownup slipper to my little boy. We got the plain gray version, no crazy colors.  Now he's glad to wear them and no more complaints about how he's not a baby any more!
