BRS 1000™, Rearfoot : A highly durable carbon rubber we invented for use in out-soles. 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...

Modified Mesh : Modified mesh with a inner sleeve that hugs the foot for a dynamic, sock-like feel.

Molded Sockliner : Underfoot inserts which are molded based on the curvature of the foot for a closer fit, to provides additional cushioning and comfort.

Nanoply : A seamless, wafer-thin material which hold the foot in specific areas while maintaining excellent breathability.

Nike® Free Sipes : A gender-specific flex grooves midsole cut to produced a barefoot-like flexibility while maintaining stability.

Phylite™, Midosle : Nike's lightweight mid-sole material designed for a resilient ride with enough durability to double as an out-sole.

Stroble Last : The upper is attached to a thin material that is patterned on the shape or silhouette of the midsole. Traditional strobel lasts use a thin cloth material, while newer variations use a thin sheet of EVA for a more cushioned feel.

Transtarsal Flex Grooves : Deep cuts flex grooves which runs diagonally under the midfoot area for increased flexibility and mobility to increase foot strength.

Waffle Lugs : Built into the Phylite's outsole, to increased cushioning upon impact.
