【英语时差8,16】防臭袜子-上（在线收听）

Check out my new high-tech socks! They look like boring old socks,Dohn,what's so high-tech about them? They are woven from an odor eating material that also kills athlete’s foot fungus. Not only that, but the treatment in the fabric survives washing and will last the life of the socks. Neat!I've had odor eating insoles before. The insoles are latex pads that fit inside your shoes and contain activated charcoal. Activated charcoal is basically carbon with a strong ability to bind and neutralize other substances– like the sweat from your foot, or odor causing bacteria. But as more and more stinky substances are neutralized, the charcoal becomes used up and the insoles begin to lose their effectiveness. So how come your socks don’t lose their power like my insoles do?
