The natural cedar wood soles are thin strips of wood on a cotton canvas. They allow an immediate adaptation to the shape of your feet. Our cedar wood soles are bactericidal and fungicidal. Cedarwood works naturally against fungi and bacteria, which prevents the appearance of mycoses. Due to its absorbency, wood collects sweat and neutralizes bacteria that cause unpleasant odors. They prevent the feet from warming up and isolate cold and hot. Instructions for use: the wood side should be placed in contact with the foot. Care advice: gentle wash in warm water with a little Marseille soap or shampoo. Drying on the wood side down. Do not expose to the sun or heat.
