Ultra-long distance mixed terrain Upper: XDiMESH multidimensional mesh (highly breathable and durable) Midsole: Supercritical foam midsole (enhanced cushioning and rebound) Outsole: Vibram® Megagrip with Traction Lug and Litebase technology Lining: Breathable anti-bacterial lining Built for ultra-distance performance, inspired by the legendary endurance race TORX® 330 and field-tested by Kailas FUGA athlete Franco Collé. Upgraded with Vibram® Traction Lug and Litebase technology, providing up to 30% more traction and 25% more propulsion while being up to 30% lighter than standard outsoles. Dual-depth lug design delivers precise grip response across mixed terrains—6mm lugs on the side for agile turning and stability, 4mm central and rear lugs for propulsion and braking. Supercritical foam midsole offers lasting cushioning and consistent energy return, 23% higher rebound and 21% thicker cushioning (vs EX3), significantly reducing joint pressure over ultra-long distances. XDiMESH multidimensional mesh increases airflow by 40%, keeping feet cooler and drier, reducing blister risk, and improving overall comfort for long races. AWS 3.0 two-section lace tightening system locks the forefoot securely to prevent in-shoe sliding and black toenails during long descents. Ergonomic design enhances forward drive and stability, with mud-draining channels to maintain traction in wet and muddy conditions. Heel-to-toe drop: 5mm Lug depth: 6mm / 4mm Weight (EU42): 285g (25g lighter than EX 330 Gen 1)
