Arch Bridge : A gender-specific mid-foot component helps smooth the transition through propulsion.

BRS 1000™, Heel : A highly durable carbon rubber we invented for use in outsoles. 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™, Midsole : Nike's unqiune midsole foam which will provides a firmer road feel that delivers plush, resilient cushioning.

Cush Pad : Located at the bottom lateral heel. A gender-specific highly decoupled unit which reduces shock at impact and reduces the degree and rate of pronation.

Dual-layer Ortholite Sockliner : Insert with Fitsole geometry sits underfoot and provides additional cushioning and comfort.

Flywire™ : Is a thread, composed of Vectran, and developed by Nike, used in the upper of a shoe. The goal of Flywire is to minimize weight and maximize support.

Nike + : A pocket under the sockliner for secure placement of Nike+ sensor. Connected to iPod nano, information on time, distance, calories burned and pace is stored on iPod and displayed on the screen; real-time audible feedback also is provided through headphones.

Nike Rideliner : A full length strobel last construction that is composed of a soft polyurethane foam for direct cushioning under foot.

Open Mesh : Covers large expanses of the upper which allows the foot to breathe which keeping runners going every step of the way.

TPU Overlay : Thermoplastic Urethane : It can be fine-tuned for optimal stiffness and is used to make stabilizing plates.

Waffle Fill™, Forefoot : Rubber compound outsole for enhanced traction.

Zoom Air™, Heel : Consist of a network of thread, plastic and pressurized gas, 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 : Air-Sole® : Those little bags are based on the following formula: Cu=U+CG (Cushioning equals urethane bags filled with compressed gas). Maybe it's not E=MC², but it will do more for your feet than Einstein ever did. It says that because the gas molecules are larger than the pores in the urethane membrane, air can't escape. The result is our light, protective cushioning.
