For the last three winters I've read about the advantages of wool socks but not paid attention because a double shot of cotton socks had worked for me. This Christmas, my wife gave me a pair of Cannondale wool socks and I tried them for the first time today. Love. Them.
In this temperature range I would have normally had on two pair of cotton socks and my toes would have been a bit chilly by the end of the ride and the rest of my feet would have been a bit sweaty once I hit the office.
With the one pair of wool socks today my feet stayed warm for the first five miles and then were just a touch cool after that. I was comfy enough for the whole ride and my feet stayed nice and dry. Okay, I'm sold.
