On a quick mission or multi-day trek, the Arc'teryx® Kopec 2 Mid GTX is a supportive solution that won't hold you back. An outsole and lugs made with Vibram® Megagrip offer assured traction on any surface-flat or steep, dry or wet-and a GORE-TEX®-lined upper keeps water off your feet and lets them breathe. This WPN PFC-Free performance shoe is built with recycled Cordura fabric and a Gore-Tex® Invisible Fit membrane for breathable waterproof protection. Reinforced with thermoplastic polyurethane (TPU) overlays and a stretch woven collar, it balances durability and comfort. A super-critical foam midsole pairs with a polyurethane (PU) foam base containing 50% Susterra plant-based content for eco-conscious cushioning. Inside, a mesh top cloth treated to help maintain freshness supports all-day wear, while a compression-molded Ethylene Vinyl Acetate (EVA) platform and molded rubber toe cap add resilience and protection. The mid-height collar blocks debris and provides extra ankle support for rugged terrain, especially with a pack, while a wider fit and more responsive midsole make the Kopec Mid a comfortable, supportive ride for hikes of any distance.
