Comfort is a key part of your running program. The Nike Revolution 6 gives you the most comfortable fit with a soft upper made from 20% recycled material and contact points on the heel and tongue for easy on and off. It's softer than the previous model with foam that creates a natural piston effect for flexibility. With its simple yet classic styling and bold logos, it's ideal for running or everyday use. Soft mesh material is placed in the forefoot and along the collar for a supportive and comfortable feel. Additional overlays throughout offer added durability. The full-length foam midsole offers a softer stride than the Revolution 5. The outsole design is computer generated creating a natural piston effect as you run for added cushioning and flexibility. It features a full-length rubber outsole for durable traction. Contact points in the heel and tongue provide a natural feel when you put the shoe on or take it off.
