The 1906W, 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 1906W’s knit upper design, which features synthetic overlays in a distinctive webbed pattern. This updated take on the era’s design conventions offers a refined execution of high-performance heritage.
