LIGHTWEIGHT AND BUILT FOR SPEED. Designed to make fast go faster, the Nike Zoom Gravity is built to take you from quick tempo runs to winning races. Snappy forefoot propulsion and grippy, multi-surface traction combine to optimize your stride, and a multi-color sockliner and outsole give you a wild look for your wild run. Benefits Responsive Zoom Air unit in the forefoot gives you that propulsive, snappy feeling. The lifted height along the midsole makes room for more cushioning inside. Dual-density foam with a soft core in a firm carrier delivers a comfortable, stable ride. Springy outsole rubber on the heel provides durability and traction on all surfaces. Higher heel with foam on the sides creates a cupping sensation and adds stability.
