Hanwag Sirius II GTX Alpine Shoes

The Hanwag Sirius II GTX is a firm and versatile alpine boot designed for demanding touring. The clamp loop allows for different tight lacing of the front and upper part of the bootleg. The hand-raised, circumferential scree protection safeguards the upper material against wear and stabilizes the boot shape.

The ultra-thin and lightweight GORE-TEX membrane, made of stretched, microporous PTFE (polytetrafluoroethylene), is particularly suitable for warmer climates. The lining is waterproof and highly breathable.

With a crampon-resistant sole, this boot is compatible with fully automatic crampons. It falls into category D, making it suitable for high alpine tours, selective glacier, ice, and firn tours in pathless, extreme terrain, or for ice climbing. The stiffness of the sole, the rounding of the sole for good rolling, and the shaft construction determine the model's positioning within categories A to D.

D indicates a very firm and fully crampon-resistant boot (step-in/automatic crampons), C indicates a firm but conditionally crampon-resistant boot (strap-on/semi-automatic crampons), B indicates a firm hold with a solid but flexing sole for trekking and hiking, and A indicates a soft, very well flexing structure.
