The Shadow 11, engineered for support, is perfect for the bigger runner. Its wide base, breathable upper and smooth ride will make many a training run joy. The visible rearfoot grid provides superior cushioning and stability by centering the heel on impact. The compression molded EVA midsole provides increased shock attenuation, responsive cushioning and durability. The SRC impact zone and HRC forefoot cushioning provides shock attenuation at the heel strike and toe-off stance. The blown rubber lateral forefoot outsole provides cushioning and flexibility for a smoother toe-off.
