The Nike Zoom Fly 5 Premium is a neutral running shoe for both training days and competitions. The shoes offer you comfort and reliability but at the same time give you a springy and fast feeling. The upper is made of lightweight, breathable mesh that perfectly hugs your foot and feels soft. Four individual pieces of fabric are placed in the midfoot that are integrated with the laces. When you tighten the laces, the fit becomes tighter and you experience a firmer feeling. The newly added ZoomX foam in the midsole makes the shoe feel lighter and more responsive. The shape of the foam offers you support for the three phases of acceleration while running. Flexibility when your foot lifts off the ground, a smooth experience when your foot moves forward and cushioning when the foot hits the ground. The midsole also contains a carbon fiber plate, also called a Carbon Fiber plate. This plate works like a kind of spring. It propels you forward while running and contributes to the very responsive feel of the competition shoes. The base is slightly wider at the forefoot and heel which provides more stability so you can make turns and long distances with confidence. The rubber outsole provides extra grip and strength.
