We recommend putting your shoes in a laundry bag and using a mild detergent, not fabric softener or washing powder. Before wearing for the first time, we recommend treating the shoes with a product intended for textiles, for example GoGoNano Protect or Goldenmix Shoe protection. They make the shoes repel water and dirt, and the shoes are easier to clean later.
