The Scarpa Phantom 8000 Thermic HD is the only high-altitude mountaineering boot with heated insoles. Designed in conjunction with Nirmal Purja for 8000-metre peaks and polar expeditions, THERM-IC Thermal Transfer Technology (powered by rechargeable power banks) heats your soles to prevent frostbite. Simply press the buttons to feel a boost of warmth.

Besides these heated insoles, this B3 mountaineering boot boasts other unique features designed for the world's toughest environments: waterproof YKK® Zips make this the only fully waterproof mountaineering boot; WinTherm thermoregulatory technology reflects heat inside the boot and regulates temperature to prevent overheating and sweating; and the combination of Carbon Tech III SL, Aerogel – an extremely efficient thermal barrier developed by NASA – and 5 mm cork reduce heat loss through the sole to a bare minimum. All to keep you as warm and dry as possible.

The Scarpa Phantom 8000 Thermic HD has everything you need to survive the coldest places on Earth. And with its unique heating technology, it's the only shoe on the market that can provide extra warmth when you're at risk of – or have – frostbite.

Details:

• THERM-IC Thermal Transfer Technology comes with two power banks (5000 mAh and 10000 mAh), a connector, a charging cable, and one pair of heated footbeds.
• PrimaLoft® Gold Eco Insulation traps heat and breathes like down but, unlike down, insulates even when wet to keep you warm in extreme environments.
• An HDry® waterproof-breathable membrane is laminated to the upper, eliminating the space where traditional membranes allow water ingress to keep you drier and warmer.
• Ecorepel® Bio Schoeller® gaiter is a textile weave that mimics the water-repellent structure of plants, creating permanent water-repellency that never needs to be refreshed with chemical DWR treatments.
• WinTherm technology reflects heat whilst regulating temperature.
• Carbon Tech III SL, Aerogel (an impenetrable thermal barrier developed by NASA), and a 5 mm cork midsole trap heat.
• Waterproof YKK® zips preventing snow, ice, and water from entering through the zips.
• Sock-fit XT tongue combined with the new fast lock lace system and fast strap closure makes it even easier to get a close, precise fit, with no pressure points over the foot.
• RECCO® Reflector bounces back search-and-rescue signals, making you easier to find in an avalanche, whiteout, or other emergency.
• The inner boot can be used as a warm basecamp slipper.
