This looks like the solution for my summer foot 'issues': some inventive Brazilians have locked on to the fact that copper has antibacterial effects, and are starting to put it everywhere that icky stuff grows, like socks for example. I've been poked by the fine wires in my stereo cables, and weaving that stuff into my socks sounds like a torturous footwear event waiting to happen, but, hey, if it helps against athlete's foot, I'd like to try it.
