Rocket DFS GTX is a fast hiking shoe, dynamic and reliable even on the most difficult trails. Rocket DFS GTX adopts the innovative Vibram Traction Lug technology that improves traction and grip by 25% thanks to the special design. The upper has a crossed rib structure and is protected by a 3D print layer. The exclusive AKU Dual Fit System (DFS) technology, here realized in the version for speed hiking, allows you to vary the degree of precision of the fit by simply acting on the two different lacing systems. It is built with AKU Elica Natural Stride System technology to promote biodynamic efficiency.
