Like the 2002R and the 860v2, the 1906R has 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 can also be seen in the 1906R's upper. Namely, it incorporates a mesh with open holes and a series of curvilinear synthetic overlays. This quirky take on the design conventions of the era offers a refined rendition of high-performance heritage.
