Remove excess dirt with a clean cloth and warm water. For caked on dirt and mud on the soles, make sure the mud/dirt is dry and use a bristle brush and some warm water to remove it all. You can also remove the laces if they’re dirty and place them in a mesh bag and wash in the washer. For the uppers, you can use a mild soap and some warm water and a brush to clean them. Rinse with water. For insoles, you can also remove those and scrub with warm water and soap and allow them to air dry. To dry the whole shoe, place it somewhere with a neutral temperature and allow them to air dry. Never dry in a dryer or with high heat, as this can ruin adhesives and ruin their shape.
