DesignThe Nike Lunarfly+ 2 Shield Running Shoe has a robust heel counter for an improved fit around the heel, and a notched innersleeve wraps around the foot for a plush, breathable feel and easy on and off. A lightweight BW2 mesh upper is reinforced with soft yet strong microfiber overlays, and a water-resistant coating protects the foot in poor conditions. Cushioning: Soft meets springy. The Lunarlon cushioning system is made up of a soft yet resilient foam core encased within a supportive foam carrier for a unique, lightweight blend of ultra-plush cushioning, springy response and support.

Environmentally preferred mix of rubbers in a Waffle pattern on the outsole for durability and traction. Nike+ ready
