Altra Golden Spike - US11M A true XC spike, the Altra Golden Spike is a shoe that has grown on me quite a bit after a few runs. Running through all terrains, it runs smooth as butter through grass or all-weather tracks, a firm road flat through dirt, and a super firm ride on concrete. The shoe almost seems to be best described a feeling track spike that carries over grass and dirt incredibly well. Stack Height: 15mm / 15mm Drop: 0mm Classification: Cross Country Racer, Minimal Trail Racer DOES NOT COME WITH ORIGINAL SPIKES or TOOL
