Action/Raction Technology™ : When using the ultra-efficient Land-Lever-Lift midfoot or forefoot running gait, the technology absorbs and then returns your own energy back to you. It's not fancy technospeak, and it's no gimmick. It's a revolutionary way of building a running shoe based on Sir Isaac Newton's third law of motion – "For every ACTION, there is an equal and opposite REACTION." Loosely translated, it means you get a boost of forward energy with every single stride you take.

Carbon Rubber Heel : Engineered for high mileage durability.

Dual Density Posting : Located at the medial midfoot to forefoot and is a higher density material engineered to slow the rate of pronation.

EVA : An industry standard midsole material designed to offer durable cushioning.

High Density Rubber : Utilized in the forefoot and is intended to provide a long lasting outsole.

Midfoot Support Chassis : Chassis for added stability.

Sockliner : To reduce underfoot friction with anti-bacterial properties.

Textured Outsole : Utilized throughout the shoe and is designed for additional traction.
