Air Zoom™, Rearfoot : Two layers of nylon fabric, joined by densely packed fibers, are sealed inside polyurethane. The unit is inflated; pushing apart the fabric and creating tension on the fibers. What does that mean? Zoom Air works by using stress of the shoe's wearer, absorbing it, and refracting the same stress which helps the Zoom insert retain its shape and buoyancy, allowing for quick responsiveness in performance venues, the result is a low-to-the-ground, hyper-responsive speed cushioning you can feel. And it does it in less space than other Air-Sole units.

BRS 1000™, Rearfoot : A highly durable carbon rubber we invented for use in out-soles. BRS stands for Blue Ribbon Sports, which was our name before we came up with Nike. The tie-in? Both BRS and Nike last ... and last...

Cushlon LT, Midsole : A lightweight version of Nike's Cushlon midsole foam that delivers plush and resilient cushioning : Cushlon : Nike's unique mid-sole foam which will provides a firmer road feel that delivers plush, resilient cushioning.

Duralon™ Extra, Forefoot : Extra thickness of Nike's super light forefoot Duralon rubber for added protection at toe-off.

EVA Sockliner : Ethylene vinyl acetate : For great step-in and motion comfort.

Strobal Last : The upper is attached to a thin material that is patterned on the shape or silhouette of the midsole. Traditional strobel lasts use a thin cloth material, while newer variations use a thin sheet of EVA for a more cushioned feel.

Ultra Lightweight Mesh : Covering the upper in a super lightweight breathability mesh package with a seamless midfoot saddle to provides an exceptional fit and comfort.
