Alpina blends their unique InTemp Heating system with a mountaineer’s boot for year-round comfort that also removes the feeling of cold feet in winter weather. Powered by a rechargeable battery, the temperature can be set to 45°F or 55°F at the touch of a button for up to four hours warmth.
The integrated heating pad sits around the toe of the boot and connects to the battery pack on the outer cuff. By stopping your toes from going numb, blood flow keeps the rest of your foot warm, ensuring you can spend a long day outside. A charging point on the inner cuff allows for quick and easy re-charging.
The leather outer provides strength and holds the form of the boots and the Sympatex® water-resistant membrane protects the foot from unwanted moisture. Built on a mountaineering last, the Vibram® sole delivers unrivalled firmness, ensuring a steady hold on any and all surfaces, no matter how challenging. Ball-bearings on the lace guides prevent friction and unwanted wear.
A removable insole results in an extra half-size (when removed), allowing you to vary the thickness of your socks.
