I had a history professor who was an avid cyclist. He would do incredibly long rides all the time. One day, I was talking to him about his rides and he had mentioned something about wet socks in the rain. He said he hated the feeling and couldn't figure out a way to fix it. One day, on a rainy ride, he stopped in a fast food restaurant to get some food and dry off a little. After his food he went into the restroom to take care of business. The restroom had one of those hand dryers for after washing your hands. He put two and two together and dried his socks. He wrapped his socks around the opening of the hand dryer and put it on a few cycles and after, his socks were dry and warm. I don't know how practical a solution that is, but I thought it was pretty clever. He was such an awesome professor.
