Product descriptionNEVERCOLD toe warmers are used inside the footwear as a comfortable and effective source of additional heat. The heating pad has an adhesive surface, which helps it stay in place between the sock and the sole of the shoe. NEVERCOLD toe warmers are small pillow-like bags made of porous material, with a mixture of vermiculite, iron powder, wood powder, activated carbon and salt inside. When the sales package surrounding the bag is opened, the mixture can react with the air, causing heat to form. The reaction continues on its own for 9 hours. Two pieces in the package. Heat generation can be stopped by moving the bag to an oxygen-free place, e.g. an airtight minigrip bag, so you can continue using the heater later.
