Air Zoom Structure 21 Running Shoe - Men's

Whether you're a longtime Structure devotee or you're newer to this bastion of stability in Nike's ultra-light, ultra-flexible family of trainers, you'll be logging miles with more support and less bulk when you pull the new Air Zoom Structure 21 Men's Running Shoes on your feet. Among lighter, gym-focused options, the Structure stands firmly in the running corner, built with springy EVA foam that's eager to take on half marathons, team relays, and track workouts alike. New for this year, Nike reshaped the base of the shoe to provide a more even platform for landing, encouraging a neutral foot strike for those with less stable feet.

Nike has been ahead of the curve in terms of upper technology for years now, and it once again delivers an almost futuristic fit that early Structure wearers will find unrecognizable—however, rest assured that any lingering nostalgia for the old stitched overlays-and-mesh setup will quickly vanish when you slip your foot inside the Flymesh upper and mesh inner sleeve. The construction wraps securely around every angle of your running-scarred feet, offering stable support that promises to become the new standard. These stretchy, breathable fabrics work with Nike's Flywire around the instep to blend support with security for an extremely adaptable fit.

Underneath your foot, the Structure's namesake Nike Zoom Air pocket sits subtly under your forefoot, providing an airy spring every time you land and push off. A honeycomb tread pattern provides traction on slick roads when everyone else is taking the day off, and EVA foam lends a plush feel that makes the shoe an excellent choice on long-run Sundays and race days alike.
