Air Zoom Structure 21 Running Shoe - Women's

Jump into a local race with a girlfriend for the fun of it or lace up for your regular Saturday run with the Nike Zoom Structure 21 Running Shoe on your feet, and you'll enjoy a mix of cushioning and support whether you're logging 3.1 or 13.1. The Structure's been a loyal part of Nike's running line for well, two decades now, and though just about everything about the shoe has changed in the last twenty years, its subtle blend of support and springy Zoom Air cushioning haven't.

Made for runners who need a little extra stability in a shoe, but don't want to run with bricks on their feet, the Structure now promotes healthy biomechanics using a wider base, as well as its signature dual-density cushioning. By providing more ground contact, you have a stabler platform on which to land and push off, plus firmer EVA foam along the inside of your foot, where overpronation occurs. Along the uppers, Nike's Flymesh upper wraps around the lumps and contours of your foot for a nearly custom fit, its airy flexibility countered with supportive Flywire around the instep for security where you need it most. Inside the shoe, an inner mesh sleeve cradles your foot in a breathable "sock" that still allows your toes to stretch and splay while you run.
