The structure of this shoe is quite good. They are comfortable, well-supportive, and cushioned enough. Their greatest detraction is their aesthetic/upper design. The sole and heel are well-made, and the tongue is plush (unusual for Nikes these days), the upper, however is INCREDIBLY CHEAP. The ribbed/webbed structure beneath the thin upper mesh is cheap foam and the entire upper feels as though it would abrade from the slightest friction in the gym and/or after a few short runs. I do not recommend this shoe. Another example of profit-hungry Nike opting for cheaper materials under the guise of \\"breathable mesh upper.\\" Also, am I the only one annoyed by marketing bulls*** like \\"Lunarlon Ride,\\" \\"Fly-Wire,\\" and \\"Dynamic Support\\"? Call it what it is: cheap, run-of-the-mill foam, annoying little strands of twine, and a bunch of rubber and foam and s*** that cushions or supports you whilst you run. Nike marketing is ridiculous.
