The 1906R. like its cousins the 2002R and the 860v2. is led by a sole unit featuring 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 design. which features open-holed mesh and a series of curvilinear synthetic overlays. This distinctive take on the era's design conventions offers a refined execution of high-performance heritage.
