Breathable textile helps your foot stay cool. The material hugs and supports you through every step for extra support and comfort. A plush, padded collar helps reduce heel slip while you move. The large forefoot Zoom Air units respond to every step. Because it's not fully enclosed, the Air unit can move with your foot, allowing for better energy return when you push off through your swing. Piston spikes and a data-informed traction pattern give you exceptional grip. The spikes are placed under the Zoom Air units and are designed to compress with pressure for better energy return and added comfort throughout your round. Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. Gusset on the tongue makes it easier to take your shoes on and off while also adding extra side-to-side support.
