Features:

• Behind the Design This Structure 25 celebrates "The Joggers Manual," a pamphlet written by Bill Bowerman that gives instructions on how to jog and the benefits that come with it. The colors nod to the book's cover, the stitched-on Swoosh logo harkens back to Bill's days of meticulous tinkering when it comes to training—not straining—and the Swoosh logo material mimics a track's surface texture. Check out Bill's signature on the side and a special message on the inside of the tongue that reminds you all that matters is movement.
• Support: High The more supportive the shoe, the more stability it can give to your natural stride. A combination of tuned support and intentionally placed cushioning helps you feel secure with every step. The Structure 25 is the most stable shoe in Nike Running. Updated foam midsole works with wider midfoot support and an increased rocker to give you a more stable platform underfoot and smoother transitions from heel to toe.
• Cushioning: High The more cushioning that you have underfoot, the softer and more comfortable your running experience can be. Cushioning helps soften impact as your feet hit the ground. New and improved foam on the midsole provides a soft and comfortable feel as you log your miles. High foam stacks help keep you comfortable. Shaped like a rocker, the foam provides support for the 3 phases of a runner's stride. It offers flexibility when your foot rises off the ground, a smooth ride when your foot is moving forward and cushioning at ground contact.
• Responsivess: Maximum The more responsive the shoe, the more energy return you can get back with each step. Whether you want to run a little bit faster or with a little less effort, responsive shoes help give you slightly more spring in your step to get more out of your run. A Zoom Air unit in the forefoot offers responsive cushioning. Every step helps create energy return to help drive you forward with a springy, responsive sensation.
• Accommodating Fit The accommodating forefoot allows you plenty of space to spread out your toes. The wider forefoot complements a wider base and smooth ride. Added structure and containment around the heel provides a more support fit.
• What's New About the Structure 25? Nike added even more foam than our previous Structures, with better support and comfort than its predecessor as well. The new and improved foam underfoot helps give you support. Nike softened the materials on the inside of the heel, collar and tongue, so that any part of the shoe that’s touching your ankle feels smooth and comfortable.
• Single-layer mesh provides breathability and durability.
• Durable rubber sole has grooves in the forefoot to create flexibility, and vertical grooves down the side help create stability.
