The Nike Dual Fusion Run features built in dual cushioning, ideal for neutral runners, combining firm and soft foam for a striking balance between soft plush cushioning and firm support underfoot during runs. The midsole is quite flexible, designed to provide a more natural, freer range of motion during your running gait, with the softer foam on top for immediate impact absorption and a firmer cushioning compound underneath for enhanced stability and support. The outsole features a waffle pattern design outsole to provide excellent traction, whilst specifically placed carbon rubber offers better durability on high wear areas.
