Good Stuff


From Uzi_does_it

from AZ

I wear these socks on the job and when hiking. The socks are warm, comfortable, and keep your feet dry. However, at 6'5" tall they are not over the calf (OTC). At my hight they fall a little short... about mid-calf in my case. In my case at least I think I will stick with the Cold Weather Crew Sock.
