3. Protect them from the elements
Don’t leave your shoes out on the porch to bake in the sun for days. The sun will help your shoes dry, but it will also start to degrade the materials if you leave them for too long.
Also, while it’s convenient to have a spare pair of shoes in your trunk, excessive temperatures can harm them there as well. Don’t leave your running shoes in your car for long periods of time. For obvious reasons, you also don’t want to abandon them to the rain or snow.
4. Clean them if you must, but never put running shoes in the dryer
Some people are obsessive when it comes to the cleanliness of their shoes, but deep cleaning isn’t always necessary.
Many runners prefer to keep their shoes out of the washing machine and clean them by hand—if at all. If you absolutely must wash your shoes and don’t want to use the old rag-and-toothbrush method, the washing machine is permissible only if you use the cold cycle. Hot temperatures can damage the glues that are used to hold shoes together and will shorten their lifespan.
If you do wash your shoes, don’t put them in the dryer. The heat will damage the shoes. Refer to #2 on how to dry your shoes.
