Toe socks are a wonderful invention. They are like gloves for your feet. They come in many different colors, and yes for those picky people with Feelings about socks, I believe they come in white. They're great because they separate your little toe, second smallest toe, and middle toe. They also eliminate that really annoying my-toes-are-next-to-each-other feeling.
And, best of all, they make great socks with sandals.
