Disclosed is a breathable insole heater element (12, 40) for footwear. The heater element is formed by photochemically etching a porous metallized fabric, e.g. nickel-metallized polyester woven fabric. The heater element is embedded in or laminated in an insole for an article of footwear such as a shoe or boot. The insole may be cut to size as desired. The insole may include microencapsulated agents such as fragrances, perfumes, microbials or insect repellents. The microcapsules may be activated to release the agents due to the heat generated by the heater element in operation. |
