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.

Beveled Heel and Toe : Helps guide runner easily into the midfoot/forefoot.

Beveled Lugs : Smoother, stable feel that is more gradual in the forefoot.

Carbon Rubber Outersole : Increases durability.

EVA : Single-density, high rebound EVA that stabilizes all foot types.

Wider midfoot/forefoot/Lugs : Adds stability and creates a softer feel.
