To preserve the shape of your shoes in the long-term, we recommend using shoe trees. While plastic shoe trees are the most affordable option, a pair of cedar shoe trees will do a better job absorbing moisture (which prevents the toes from curling up), and can also deter moths. Plus nothing beats the smell of fresh cedar.  *Most shoe trees are sold in sizes like “small” and “medium” which correspond to a range of numerical sizes. If you find yourself right on the edge of a size—for instance, between a medium and a large—it’s a safer bet to size-down so that the shoe trees won’t stretch out your shoes.
