Foot Warm-Up® will help keep your feet warm and are packaged in pairs. They work simply by shaking the ingredients together. They are designed thin so as to fit in between a footbed and the sole of the boot (NB must not be used in direct contact with the skin). The "air-activated" Foot Warm-Up® is made of all natural ingredients, environmentally safe, odourless and will supply up to 6 hours of comforting heat for cold feet.
Average heat 38ºC (100ºF) - 40ºC (105ºF) for up to 6 hours.
Each double pack (one for each foot!) measures 12cm x 17cm.
