Mittens for your feet

A few weeks ago my daughter who is 13 and exceptionally bright was sitting in the kitchen putting on toe socks. If you dont know what these are they are like gloves for your feet. Each toe has an individual spot to go in. I walk into the and she says you know what they should invent? What I say? Mittens for your feet.

Um yeah Sarah, I think they already have those, they are called socks.
