No matter what your goals are, pick up a pair of the Jordan Express to take your training to the next level. Mesh with perforated, flexible foam is light and ventilated. Synthetic wing wraps around the heel for stability. Full bootie construction for a one-to-one fit. Injected Phylon unit sole for a lightweight, cushioned ride that's durable enough to double as the outsole. Injected unit sole is raised in areas for improved traction and cored out in lower-wear areas to reduce weight. Strategically placed rubber pods for grip and durability.
