Rated 5 out of 5 by from What a sock! Just picked up these babies the other day; outstanding socks. They're soft, cushy, breathable, supportive and, most importantly, they offer that incredible anti-microbial effect which destroys my otherwise ungodly foot odor. I'd marry these socks if it was socially acceptable.
