If it is a model with a rubberized PVC finish, you can clean them with a damp cloth (eg Materia Solid or Atom Supercell).
We do not recommend putting them in the washing machine, just put the insoles and laces. For the shoe, pass a damp cloth with neutral soap. In the case of putting the whole shoe, separate the insoles and the laces and put the shoe in a mesh bag. To clean the sole: fill a quarter of a glass with ethyl alcohol and the rest with water. Rub the mixture with a cloth. Let dry at room temperature. Do not use detergent.
Extra recommendation: make balls of paper and put them inside the shoes to absorb moisture and keep their shape
