I absolutely do. It helps drying and prevents the old boot smell, as well as drying the shoes off in a reasonable amount of time.
@Cleanneon98 I don’t know if this works, but baking soda in the laundry takes out all the funky smell in my clothes, socks, and towels. I don’t know if it’s worth it to give them a dunk in a baking soda + water solution.
I would also change the insoles, and ring your buddy and let him know you can smell the stink on his feet miles away.
