The Cloudalpine Waterproof: Lightweight trekking boot | On 。Running-inspired technologies reimagined for trekking are what define the On Men\'s Cloudalpine WP. It is a lightweight, agile trekking boot for long trips in mountainous and rough terrains. The Cloudalpine has a durable yet lightweight upper with a ripstop vamp and reinforced mudguard which combine to provide abrasion-resistant protection, without adding excess weight. An innovative slide lace locking system keeps them secure around the ankle. Made of injected nylon with 15% carbon, the Cloudalpine’s Speedboard provides stability and support in the most technical and demanding terrains. On’s distinctive CloudTec midsole softens each step, and the rocker shaped outsole creates a remarkable roll-through from heel to toe.
