| • | For runners with a neutral to moderate gait and who are looking for a lightweight performance trainer that provides superior shock protection on impact combined with the responsiveness of a long distance racing shoe. |
| • | WaveSpring® cushioning system - two springs in the forefoot and one spring in the heel provides maximum energy efficiency in conjunction with a high level of cushioning that is very responsive for racing. The WaveSpring® is a low profile, lightweight spring made of stainless steel. |
| • | An open air mesh vamp provides maximum breathability, comfort and fit. The midfoot is supported by molded support straps that are tied into the lacing system. This improves support and resists stretching without interfering with the breathable properties and comfort provided by the mesh vamp. |
| • | Two piece pod construction using compression molded EVA incorporating a single lightweight WaveSpring® in the heel and dual lightweight WaveSprings in the forefoot. The pods are connected together with a fiberglass reinforced nylon shank for midfoot stability. |
