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-mounted, 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 especially suitable for warmer climates. The lining is waterproof and highly breathable. The boot features a crampon-resistant sole for fully automatic crampons.

This shoe is categorized as 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 blast (how far the sole is rounded off to allow good rolling), and the shaft construction determine how a model is positioned within the categories.

• 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 and solid but flexing sole for trekking and hiking
• A = soft, very well flexing structure
