Mammut Alnasca IV Low GTX

The Mammut Alnasca IV Low GTX is a precision-engineered approach shoe designed for those who demand confidence on technical terrain, from steep hikes to demanding via ferrata routes. Built with a breathable Air-Mesh upper and integrated with a GORE-TEX membrane, these shoes ensure your feet remain dry and comfortable regardless of unpredictable mountain weather. The core of its performance lies in the FLEXTRON propulsion plate, which offers the lateral stability and stiffness required for precise edging on small footholds. Combined with a cushioned EVA foam midsole, the Alnasca IV strikes the perfect balance between a lightweight feel and the rugged protection needed for long days moving toward the crag. It is the ideal choice for climbers seeking a low-cut, agile solution.

Every detail of the Alnasca IV Low GTX is optimized for durability and grip on varied alpine surfaces. The Vibram XS Trek EVO outsole features innovative Traction Lug™ technology and a dedicated climbing zone, providing exceptional friction even on wet rock. To withstand the rigors of scree and granite, Mammut has included a robust rubber toe cap and a raised rubber rand for maximum abrasion resistance. Inside, an Ortholite® insole delivers long-lasting step-in comfort and moisture management, while the standard lacing system allows for a highly adjustable, secure fit. Weighing in at just 410g (UK 8.5), these shoes offer a technical approach last and an A6 flex index, ensuring you have the support and flexibility to tackle the most complex mountain approaches with total confidence.
