Why use shoe trees? Shoe Trees do more than keep your shoes smelling aromatic. The cedar wood wicks (absorbs) moisture from the wet leather to keep the shoe soft, supple and dry. Also, a shoe with a cedar shoe tree will maintain its shape and thus its ability to support your foot. Lastly, cedar shoe trees will prolong the life of your golf shoes. Your shoes, and your pocketbook will be glad you made the investment.
