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…

Free Specific Mesh : A smealess design for breathable and barefoot comfort.

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

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

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

Strobel 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.
