Outdoor athletes looking for a light, athletic and at the same time stable fast hiking boot are going to love the terrex™ Fast R. Despite its low weight, the mid and low-cut versions offer security and stability. This is made possible by the non-slip soles made from an innovative Continental rubber compound, 3D FORMOTION™ technology for controlled descents and the shaped heel cap, which guarantees a perfect fit. The adidas boot development team have invested a great deal of time in the weight and new technical features of the terrex™ Fast R. The new TRAXION® sole is unique; developed by adidas together with Continental. The experience of the tyre specialist and the close work together with adidas made it possible to create a rubber compound with a grip that is exceptional in dry and in wet conditions. This guarantees the necessary ground adhesion at high speeds and in all weathers. This level of security is also supported by advanced three-dimensional FORMOTION™ technology in the heel zone. Two overlapping plates slide forward, back and to the side depending on ground conditions and the angle of contact. This reduces heel-to-toe velocity and equalizes uneven ground. The result is a considerable reduction to the stress acting on the knee and heel while promoting a natural sequence of movement. Two additional features ensure improved control and reduced stress during fast tours. Firstly, the foot is positioned lower in the terrex™, which gives athletes a more direct feel and more natural flex. Secondly, the complex three-dimensional heel section has a firm hold on the heel for direct transmission of energy to the ground. Weight fanatics, for whom every gram counts, choose terrex™ Fast R because every feature is designed for speed.
