Description
Thermal balance and precise support, holding steady as effort builds. Compression zones and 3D ventilation channels follow the foot's biomechanics to keep it stable, while kapok, the lightest natural fibre in the world, adds insulation without weight. Biolight, a plant-based fibre from beech wood, manages up to twice the moisture of cotton.
