Nike Air Zoom Structure 19 Flash Run Shoes This all-weather version of the Air Zoom Structure 19 is a stability shoe, designed to provide excellent support for over-pronators wrapped in a water repellent and highly visible coating. With responsive cushioning, this is a versatile shoe, which also copes particularly well with fast paced runs. A full mesh upper with a Flyknit construction and Flywire technology ensures a perfectly secure fit and provides effective ventilation.
The seamless construction removes any potential for irritation, resulting in a shoe that's extremely comfortable. An internal heel counter delivers a snug, secure fit and the internal toe tip provides structure and durability. Extra responsiveness and cushioning is provided by the Ortholite sock liner The sole performs equally as well. Dual density cushioning and wedged foam with Dynamic Support Technology ensure comfort and stability. A 3rd, firmer density foam slows the rate of pronation from the heel to the medial midfoot.
