Fans of the classic Breathe Free II and Breathe 2K10 will love the Air Max Cage. It's built on a modified-running last (like its predecessors) that is women's specific for the most comfortable and supportive fit possible. The upper is composed of lots of mesh wrapped by a single-piece TPU injected cage to provide excellent breathability along with lightweight support and stability. The midsole includes a Max Air heel unit to provide the classic Nike look along with the ultimate cushioning. Another great feature is seen in the outsole, where the high wear areas have been designed with added rubber for increased durability where you need it most. The shoe is also backed by a six month outsole durability guarantee. Offered in a variety of colors, the Air Max Cage offers lightweight performance coupled with all the stability and durability you'll need.
