Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. 2-piece plate with metal studs provides optimum flexibility and comfort underfoot to give you that ârunnableâ feel when traveling between the bases or roaming the outfield grass. An updated anatomical lace around the midfoot helps meet your containment needs. A mesh window in the upper harkens back to the iconic Nike Huarache from the basketball world to help create lighter weight compared to its baseball predecessor. Internal webbing and updated mesh provide lightweight, breathable support and containment. Layers of breathable mesh and strategically placed overlays give you a secure fit.
