The AMP climbing shoe from Red Chili fits perfectly to the foot and gives a lot of feedback from the ground. Due to its split sole construction, the shoe remains always very sensitive to friction strings. Also Red Chili is now using Vibram XS Grip sole rubber. The blue synthetic material widens only slightly and the footbed in the shoe is made of leather so that a good foot climate is ensured. All in all, a very good shoe suitable for long training sessions in the climbing hall or for friction climbing on the rock.
