Toe Socks??????????

This weekend Mary bought a pair of Toe Socks. I have never seen nor heard of these things before! They are the funniest looking things, but the more I thought about it the more they sound comfortable. Have any of you ever worn or seen these things before? She bought them because she has had trouble with a blister on one of her toes while running and they are supposed to take care of that. As I mentioned in an earlier post she is training for a marathon.
