Odor Eaters Ultra-comfort Insoles are designed to be comfortable and effective at the same time. They are lightweight, and very thin so they will not take up room in your show and make it feel tight. They are ventilated, to help keep feet dry, and they combine odor-destroying ingredients with powerful super-activated charcoal to fight unwelcome smells for an extended time. They are available in a convenient 3-pair economy pack, so you can fit all your shoes and save money.
