These solid cedar shoe trees will help preserve the shape of your shoe or boot for years to come. The cedar wood's wicking properties absorb moisture in the insole and lining cutting down on any potential mold, mildew or cracking. Shoe trees can also be helpful when caring for your footwear as the upper will be supported while brushing or polishing the leather. Instructions: When inserting, roll the tree laterally to allow the tree to easily slide into the shoe. Avoid pushing the tree down directly into the vamp, as it can damage the collar and insole of the shoe. If you're wearing wide widths, consider sizing up for your shoe trees
