Description

AKU Montagnard Work GTX – Certified Work-at-Height Mountain Boots

The AKU Montagnard Work GTX is the certified version of the original MONTAGNARD GTX: born for classic mountaineering, re-engineered for professional use. Built with Perwanger® 2.6 mm leather and a full rubber rand, it stays robust yet comfortable for long hours. Compatible with self-locking crampons, this safety boot is among the lightest and most comfortable in its class thanks to an aluminium-alloy safety toe cap (minimal bulk, generous fit) and a fabric-composite anti-penetration insert that keeps weight down. High rigidity and stability make it ideal for work at height and demanding jobs on mountain infrastructure sites.

Aim of the Product

Provide a cramponable, waterproof, certified safety boot that blends mountaineering precision with industrial protection—perfect for harsh alpine worksites and rope-access tasks.

Audience

Rope-access & rescue teams, utility/mountain infrastructure workers, and alpinists who need EN ISO 20345 S3-level protection without sacrificing comfort or climbing performance.
