if they are "smart wool" you'll do fine. otherwise, it depends. the socks you bought came with directions on how to wash.
or go back to the sock guy and ask him/them.

i have some non-smart wool wool socks, and some of them have gotten less pleasant to wear over the years, and others stand up better. try and find the washing directions that came with your socks. I throw mine in the wash. survival of the fittest!
