Fabric: 80% polyester / 20% nylon (sole) 100% Eva How to care : EVA shoes can be hand-washed using mild soap and baking soda. Wash with a cloth or soft brush and let dry in a cool shaded area. Never put your shoes in the washing machine, dryer, or dishwasher! EVA shoes are heat-formed, so they can be heat-deformed. We advise to store shoes away from direct sun or heat, as they can warp due to the EVA composition. We also advise against leaving them in hot cars.
