Crafted from various types of wood, such as cedar or limewood, shoe trees are essential for reducing creases and maintaining the shape and quality of your shoes. Most importantly, a shoe tree will help to draw out moisture (such as sweat)from the shoe after use. If you have an extensive shoe section in your wardrobe, that’s a costly investment. But rest assured you don’t need one for each pair of shoes, the time you need them the most is the hour or two after the shoes are off your feet.
