There's a love hate relationship to be had with early morning runs the frosty cold can rip the breath from your lungs and the your feet can feel a whole lot like cement blocks smashing themselves against the pavement. Thankfully the Nike Women's Air Zoom Structure 19 Running Shoe is built for providing a stable yet effortlessly fluid ride and simultaneously blends Nike's classic cushioning and stylish construction. Crafted with a seamless, Flymesh upper, the Air Zoom Structure 19 hugs your feet and ensures optimal ventilation while the flat, Flywire cables are integrated into the lacing system and ultimately encourages a supportive, glove like fit. Additionally, the full inner mesh sleeve cultivates breathability and sock like comfort and an internal heel counter assures a secure fit. Located in the forefoot of the shoe, the Nike Air Zoom unit offers low profile cushion and in turn boosts your next step forward, propelling you into a fast pace stride rather than flatly absorbing impact. The triple density Dynamic Support system is constructed specifically for stabilizing footstrike transitions and slows the rate of pronation with its firm foam midfoot insert and wedge foam in the heel.
