If you want your hiking boots to last longer, you will need to make sure that you properly take care of them. Start by taking out the footbed and rinsing it.
You do this to remove debris and any loose dirt in it. You can then wash the outside of the shoe with cold water.
Make sure to wipe away any excess water and leave the shoe completely dry. Leave it out to dry naturally. It would be best if you used the creams and sprays specially made for leather. This way, you preserve it.
Never make the mistake of using a direct heat source to dry the shoes. It will damage the upper materials and midsole.
