Footwear can be easily invaded by foul odors from sweat, foot fungus, bacteria, mildew and mold. Stinky sneaker, shoe, and boot odors will smell worse if left untreated and become a source of embarrassment. Covering up nasty footwear odors with perfumed deodorizers only result in more offensive smells and does not eliminate the problem. Smelleze Sneaker, Shoe, & Boot Deodorizer Pouch fights stinky footwear odors without covering them up with fragrances. As an added benefit, it can also be used to prevent mold and mildew in stored shoes by absorbing moisture and will also deter shoes and boots from cracking. For a breath of fresh air, simply place one reusable Smelleze pouch in each shoe and smell the difference. To rejuvenate periodically, simply heat in a microwave or place in direct sunlight and reuse. Smelleze is non-toxic, safe, reusable recyclable, natural, odorless, non-flammable and non-caustic. Smelleze is an ideal eco friendly solution for eliminating shoe odors.
