These shoes are just fantastic. Lightweight, breathable, supportive, responsive - they literally embody the best you could hope for in a running shoe. I've had them for over a year as a running shoe and also as a casual shoe and they are holding up beautifully. If they ever break, I'll happily buy the same model right away. Other Nikes don't come close. I hope they never stop making them because I will be happy to buy this model for many years to come.
