Looking for one pair of shoes that does it all? Check out the 1211s. With supportive side bolstering and lightweight, breathable mesh, these shoes do it all. In addition to their versatility, they're an improvement on the previous 1210s - with a lower stack height, a medial post, and Stability web, they keep your feet planted during the brutal left-to-right motions of cross training. To keep you comfortable while running, they feature both N-ergy (a stabilizing outer thermoplastic rim with cushioning inside) and ACTEVA® LITE, a lightweight, hi-tech foam built to cushion and resist deformation in the long run.
