An upper made from the finest materials available.
The body of the shoe is made from an extremely breathable "air-mesh". This mesh is woven as one piece front to back, not layers of material cemented together. Support and protection come from overlays of microfiber synthetic leather.

We put the material where you need it and not where you don't.
We refuse to add any decorative molding or embossing. These add weight, decrease flexibility, and prematurely deteriorate the materials involved.

A Compression molded EVA (ethyl vinyl acetate) midsole combined with secondary cushioning inserts.
The inserts are made of a rubber/EVA compound for resilience and longevity. The midsole in the Proportion II and Symmetry II models contain a "stability post" made of firmer EVA to help prevent pronation yet do not interfere with cushioning under the heel. The bottom of the midsole is unsculpted to provide a continuous planar surface from strike to toe-off.

Our outsole is made of carbon rubber for greater durability.
It's thin for lightweight and maximum flexibility. It's one-piece for superior bonding and less chance of delamination.
