Track athletes training for the 800- to 5000-meter don't need much equipment. But what they do need had better be right. That's where the Nike Zoom Rival D 10 comes in. Designed specifically for those middle to long distances it includes single-layer mesh for lightweight ventilation and no-sew overlays for support in the heel. Overlays on the toe tip and eyestays add durability when churning through those strides. An arch band secures your midfoot and an anatomically designed toe gives you room for a spacious comfortable fit.
