The 1906U features a lacing closure, side logo with loops, neutral cushion midsole, and an Ndurance outsole made of polyester and rubber. SKU: U1906NB_TWILIGHT HAZE. Like its "cousins", the 2002R and 860v2 models, the 1906 Utility features a sole with a combination of flexible ACTEVA LITE cushioning, shock-absorbing N-ergy, and segmented ABZORB SBS pods at the heel. This high-tech approach is also reflected in the upper design of the 1906R, which features an open mesh and a series of curved synthetic overlays. The distinctive interpretation of the design conventions of this era presents itself in a refined execution that is worthy of the tradition of highest performance demands.
