When you remove your shoes after a dayâ€™s wear insert a cedar shoetree. The cedar will do two things: 1) absorb any moisture and odor from normal wear and 2) keep the leather upper of your shoe from deforming as it dries.
SYL TIP: You only need one shoetree. Your shoes are the most susceptible to creasing and cracking right after you have worn them due to the moisture that has softened the leather. Once you remove your shoe after a long day, insert the shoetree, and allow your shoes to dry overnight. Repeat the process with the next pair of shoes you wear the next day.
