These socks are really thick and warm.  These are of a good quality.  I always sort of cringe when pulling on wool socks because I think they will be itchy.  They aren't.  They are warm.

What is better is that they are comfortable under hiking boots.  They have just the right warmth and thickness to protect against heavy and not perfectly comfortable boots.  I really need to get rid of the uncomfortable boots.  Columbia hikers are lightweight and comfortable.  Anyway, perfect hiking socks.
