Like the 2002R and the 860v2, the 1906R is driven by a sole with a combination of flexible ACTEVA LITE cushioning, shock-absorbing N-ergy and segmented ABZORB SBS pods at the heel. This hi-tech approach is also reflected in the 1906R's upper, which features mesh with open cavities and a series of curved synthetic overlays. This distinctive take on the design conventions of the era offers a refined rendition of high-performance heritage.
