Since mankind first walked upright we have had problems with the foot-to-ground interface - otherwise known as "Oh, my aching feet." As we have evolved, so has our understanding that we should have something under our feet, and that something must be cushy.   A great deal of thought has gone into this phenomenon; naturally, science has undertaken the project. Conventional footwear designs have addressed the pressures associated with "high-impact" activities of sport and, in technical terms, taken the vertical force and dynamically dissipated it onto a more horizontal plane.   In short, cushioning.   But there is another factor that comes into play for most runners, jumpers and pod pushers -- momentum. How do we get that spring in our step that keeps us moving even when our feet are tired? What induces us, in the last mile or during the fourth quarter, to push forward?

A. NIKE SHOX for Basketball:: Designed specifically for the player who demands a high level of cushioning, protection and lateral stability, the unique NIKE SHOX system features a contoured top plate that acts as an external heel counter while distributing impact forces to the individual NIKE SHOX columns. Each NIKE SHOX column is shaped to deform inward for stability and control while the sturdy bottom plate provides a steadfast "footprint" for the next explosive step. A TPU transition wedge compliments the internal shank plate by adding torsional stability and helping focus the flex zone of the shoe to the forefoot. If that weren't enough, the herringbone outsole pattern and dynamic fit of the internal bootie provide sensational traction and snugness to this full-court trampoline system. NIKE SHOX BB4 B. NIKE SHOX for Running:: The clean, futuristic design of the NIKE SHOX R4 running shoe says a lot about the time that went into its development. One of the biggest challenges for Nike developers was controlling the rear foot cushioning and movement of the four columns. After re-evaluating the stiffness of various plate materials and heel bevels in combination with the columns, designers found the optimum balance for each and then analyzed each pair of samples for durability, impact resilience and motion control. The result is a variable-stiffness column system based on the relative shoe size and weight of the average user. Each shoe size is able to replicate the same shock absorption characteristics for different-sized runners. Combined with a transition wedge in the midfoot, this makes for a responsive ride from heel to toe. The track-inspired upper design combines snug fit with breathable mesh in the forefoot and a plush heel collar and tongue lining for added comfort. NIKE SHOX R4

Introducing NIKE SHOX   When the foot hits the ground - typically heel first - the muscles, tendons and joints of the foot absorb a lot of the impact. Nike changed all that in 1977 when they collaborated with Aerospace engineer Frank Rudy to create the first Air-Sole units encapsulated in the midsole of a shoe. After 16 years of testing, Nike presents NIKE SHOX, its most innovative technology to date.   More than just a set of rocket booster-like columns built into the heel of a shoe, NIKE SHOX technology gives the feeling you can do more. Like all Nike technologies, NIKE SHOX, by virtue of innovative materials that absorb impact and return energy, is designed to help you push your run, workout or game further than ever. How does it work? From the midfoot forward, the NIKE SHOX product is very similar to a typical top-of-the-line running, fitness or basketball shoe. Nike uses similar midsole / outsole materials with an Air cushioning system to provide shock absorption and a smooth transition under the forefoot. Meanwhile, back at the heel, a unique system of four hollow columns of highly resilient polyurethane foam work in tandem with the sturdy thermoplastic plates above and below the columns. While the columns look like springs, there are actually no coils inside them, but rather, a geometrically advanced ribbed cylinder shaped to maximize cushioning and minimize weight.   The shock absorbing material that makes up the column is made by Hyperlast, an English company that makes joust bumpers for motor mounts and chassis frame bumpers for Formula 1 race cars. The vibration dampening affect of this material is a big part of what gives NIKE SHOX its springy ride. How does NIKE SHOX compare to Nike Air? Nike SHOX acts like a trampoline, absorbing impact and then deflecting the energy stored upwards, creating the responsive feeling of momentum, or what many NIKE SHOX wear-testers described as "BOING." There is a "spring-forward" effect that turns running into bounding.   In contrast, Nike Air is a softer, more pillow-like form of cushioning. It's a slightly more static system that absorbs impact forces and then springs back to its original shape preparing to cushion the next blow. Nike Air will continue to evolve as Nike's superior cushioning technology for outstanding impact protection. Nike Technology | What's next and what works?
