Nike Zoom Fly 4

• Nike Flyknit material is placed around the collar, providing extra stretch for easy on and off. It has a sock-like feel that helps contain your foot and feels secure.
• The upper is made with lightweight mesh for a softer, more breathable feel that conforms to your foot.
• Midfoot support arrives courtesy of 4 individual pieces of webbing that intertwine with the laces. When you lace up, the shoe gets tighter, giving you stability.
• An internal heel pod delivers a more secure fit than the Zoom Fly 3.
• Nike React technology is a lightweight, durable foam that delivers a smooth, responsive ride. It combines with an internal carbon fibre plate for flexibility in your stride.
