The Atomic Redster Heated Boot Bag 220V will get your boots to exactly the right temperature, wherever you put them on. With their integrated heating system you can choose between Hot (70°C/150°F), Dry (60°C/130°F) and Warm (50°C/122°F). You have the option of a regular DC plug or a plug that works in your car. The extractable ground sheet makes sure you won’t get your socks wet when changing before or after a race. All this plus two stowable rucksack straps and a shoulder strap make it really easy to carry.
