VERSATILE COMFORT WITH FLEXIBLE CUSHIONING. Here's to new beginnings between you and the pavement. We know comfort is key to a successful run, so we made sure your steps are cushioned and flexible for a soft ride. A strap and wraparound zip makes these shoes super-easy to get on and off. It's an evolution of a favourite, with a breathable design made with at least 20% recycled content by weight. Easy Entry Nike FlyEase technology makes it easy to put these shoes on and take them off. A wraparound zip on the heel opens up the shoe and a strap over the top secures your fit. Simple Design Breathable fabric is placed at the forefoot and along the collar for a comfortable feel. Additional skins throughout add durability. More Flexibility A foam midsole delivers a softer ride than the Revolution 5. The outsole has a computer-generated design that creates a natural piston effect as you run, providing more cushioning and flexibility. They combine for durable traction.
