Shoe Use and Care: * If footwear has been exposed to dirt or contaminants, clean immediately with a damp cloth with mild soap. Always clean before treating. * Treat the Poromeric upper with a quality furniture polish or poromeric cleaner (sold here) product on a regular schedule. This will help preserve the shine. * Allow footwear to dry slowly at room temperature only, never by a heat source. * Keep the insides of footwear dry and clean with powders and disinfectant sprays. Consider a second pair. This allows one to dry out thoroughly while the other pair is being worn.
