Trimly's cedar Sneaker Trees will extend the life of your sneaker collection. Too many sneakers fall apart and disintegrate before they should. The problem is sweaty feet. Sweat contains salts, acids, and bacteria. Overtime, these elements can rot the lining and upper materials of our kicks. Trimly's cedar Sneaker Trees are designed to wick away damaging moisture. As a result, your sneakers will look better and last longer. It's protection from the inside-out. Available in bundles of 5 and 10. Also sold individually.
