The #terrex Fast R Mid GTX. It is the ideal shoe for moving fast in the mountains. In 2015, the light, athletic mid-cut shoe gets some small but important updates such as a snug-fitting neoprene heel. Despite its low weight, the terrex Fast R Mid GTX offers great stability and reliability, which makes controlled climbs and descents possible at high speed. The FORMOTION™ unit in the heel and the Continental™ rubber outsole guarantee additional control and the necessary grip on wet surfaces.
