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 elevated brim features hand-raised, circumferential scree protection, which safeguards the upper material against wear and stabilizes the boot shape.

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

This boot has a crampon-resistant sole designed for fully automatic crampons. It falls into category D, indicating it is 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 blast (how far the sole is rounded off for good rolling), and the shaft construction determine the model's position within the categories A-B-C-D, providing an idea of the shoe's stiffness.

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