As mildew often occurs on the surface of the fabric, it is not likely to be rooted deep in the fibers. Thus, the hiking boot internal side might cope with smell rather than mildew spots. So right when you notice your hiking boots have a mildew smell, it is best to clean the inside immediately. The purpose is to expel all the smell in them.

Regularly, hiking boots come with leather or fabric lining, so the method to deodorize two materials is also different. Should your hiking boots come with leather insole and lining, you can apply the following way:

  • Prepare a leather cleaner , a horsehair brush , a dry clean rag, and a sprayer of warm water.
  • Spray a dewy layer of warm water inside your hiking boots, then directly use leather cleaner to the hiking boot inner surface.
  • Then take the horsehair brush to thoroughly scrub your footwear inside, ensuring it is clean and non-odor.

Rule of thumb

  • Ensure your hiking boot interior is dry after cleaning. It is advisable to use a boot dryer  (or hair dryer) or boot trees. Put them into the footwear.
