Alien Sky is designed for vertical terrain and the most technical trails, where precision and responsiveness make the difference. The out sole system ensures direct contact with the ground, progressively absorbing impact and providing stability and agility during pace changes. Vibram® Megagrip technology guarantees traction on rock, mud, and extreme slopes. The upper with an integrated gaiter wraps the foot, protects it, and connects it to the ground. Lightness, precision, and propulsion help overcome every limit.
