Socks, socks, socks, and more socks. I cannot stress that enough. When I see my sister meandering around in our kitchen with no slippers or socks on, it is all that I can do to refrain from gagging. I dread to think of what ends up between her toes at the end of the day. I wear socks and slippers, regardless of whether or not I am at home or not. It is an absolute must!!
