I will only do it if it is really dirty or when I am very free. Having completed the training, I will leave it for a day or night in the open air.
In my opinion, it is no harm to wash your running shoes but you have to make sure they are completely cleaned without any detergent. Then let it dry naturally but not directly expose to the sunlight. You can go to any household stores or Jusco $10 shop to buy a special hanger for shoes
