Double-stacked foam creates our most cushioned stability shoes yet. Take supportive cushioning to the next level in the Structure Plus. We stacked responsive ZoomX foam on top of ReactX foam for a smooth and secure ride. Our midfoot support system provides a stable transition from heel to toe. Plus, reflective design details throughout brighten up your route. Stability meets super foam For the first time in Nike history, the Structure's trusted stability combines with ZoomX foam, so you don't have to choose between comfort and support. Midfoot support Our midfoot support system wraps the heel and arch for optimal stability and a smooth heel-to-toe transition. Secure Mesh Upper Engineered mesh upper with a secure midfoot band gives you a contained feeling with optimal breathability. Dual-Rubber Outsole Soft rubber in the forefoot gives you flexibility while stiff, high-abrasion rubber in the heel offers enhanced durability.
