soles

Running shoes for real runners are regularly categorized into two types: stability shoes, for those who over-pronate, and cushioning shoes, for those who don't. Nike's LunarGlide+, available July 1 for $100, claims a novel mid-sole architecture described as "Dynamic Support," which eliminates the need to choose between the two types. But more impressive than that assertion is the simplicity of the design by which Nike hopes to revolutionize the industry.
