Where can i buy the best quality and cheapest Nike running shoes?

Nike is my personally choice in a running shoe, I find Nike the most comfortable with their Air technology and the shoes are long lasting and great looking.  When shopping at NikeTown I always check the clearance rack first, I've provide a link to their clearance selection.

Zappos has a large selection of Nike's for men, women and children.  Kohl's also carries some Nike shoes.

Nike continues to seek new and innovative ways to develop superiorathletic products, and creative methods to communicate directly withNike consumers. Nike Free,Nike+ and Nike Sphere are just three examples of this approach. Nikehas always been at the front of technical integration, whether it isfrom Bill Bowerman’s wife’s waffle iron outsole, the revolutionary NikePegasus, to Nike Air technology; Nike is always pushing the envelope on creativity. When it comes to creativity and functionality, Nike’s motto is “Just do it.”
