Whether you are heading out on a mountain hike, a long-distance walk or a technical trail, the AKU Alterra II GTX is developed to deliver comfort, precision and stability in demanding conditions. The upper combines durable 1.6 mm suede leather with a flexible stretch fabric, providing an optimal balance between support and freedom of movement. The asymmetric lacing system and elastic construction ensure a precise fit that adapts to the natural shape of the foot from the very first step. Liba® Smart PU protection around the upper allows the shoe to handle rough terrain and rocky sections without compromising on weight.

Waterproofing and breathability are taken care of by the Gore-Tex® More Seasons membrane, which keeps feet dry and comfortable in changeable weather conditions. Underfoot you will find the Vibram® Alterra II outsole with reliable grip and good ground contact, supported by a PU and EVA midsole that provides effective cushioning and response.

The construction has medium stiffness with a 6–4 mm nylon plate and shaped EVA, offering both support and flexibility for hikes of medium duration and intensity. The soft Custom Fit insole moulds to the contours of the foot for a tailored feel throughout the entire outing. The Elica Natural Stride System is integrated into the sole construction and supports the foot's natural movement for better dynamics and reduced fatigue on long stages. The shoe is manufactured in Europe.
