UA SpeedForm upper construction eliminates seams for a comfortable, distraction-free fit. Breathable engineered mesh keeps feet feeling cool and fresh. Internal heel counter holds the foot firmly in place over the footbed. Charged Cushioning midsole combines a top layer of soft foam over a denser base for the perfect pairing of comfort and responsiveness. Outsole uses blown rubber in the forefoot for light cushioning and high-abrasion rubber in the heel for durable traction on any surface. Wt. 8.1 oz.
