Shoe trees are devices designed to maintain the shape of shoes, preventing them from creasing and losing their form. Typically made from wood or plastic, they are inserted into shoes when not in use. The most common type is the cedar shoe tree, which also helps absorb moisture and odors. Using shoe trees can extend the life of footwear, making them look better for longer. They come in various sizes and shapes to fit different styles of shoes, including dress shoes, sneakers, and boots. Regular use of shoe trees is a simple way to care for your footwear investment.
