my mom just picked me up a pair of umm... copper socks. they're made by Aetrex and have this amazing "copper sole" technology thats supposed to eliminate 99.9% of Bacteria, Fungi, and Odor. it claims to be made with Cupron yarn, but it feels/looks like a normal sock. im skeptical to say the least. can anyone confirm these claims? im not quite sure if copper can stop the stink.
