Built for women who crave adventure beyond the beaten path, the Arc'teryx Norvan LD 4 delivers exceptional comfort and confidence on long-distance trail runs across mud, roots, and rocks. The Vibram® Megagrip outsole with LITEBASE technology provides superior traction while keeping weight down to just 217g per shoe, while the innovative 4mm mud-releasing lug pattern ensures you maintain grip whether you're powering through soft trails or navigating technical hardpack terrain. The dual-density midsole and spacious comfort fit design work together to prevent fatigue during extended adventures, while the flexible external midfoot frame locks your foot in place to prevent toe bang on descents. With PFAS-free construction and targeted abrasion resistance, these trail running shoes are engineered for women who demand both performance and environmental responsibility on their most challenging runs.
