Woolie Boolie Sock
my favorite winter sock for mountain biking but can be used anytime in the winter. They are warm, wick the moisture away from my feet and aren't itchy as you may think. In the past I have worn them in the summer because they are so soft and they never make my feet hot or sweaty. i still have my first pair and that was 4yrs ago, just bought another pair a few months ago.
