Jordan Why Not Zer0.4 'KB3'
The Jordan Why Not Zer0.4 ‘KB3’ applies a subtle spring-ready palette to Russell Westbrook’s signature shoe. The upper is constructed from slate blue mesh with contrasting lavender accents on the sneaker’s pull tabs and synthetic overlays, as well as webbing straps integrated into the lacing system. Extra-responsive cushioning is provided by double-stacked Air Zoom units housed in the forefoot of the full-length foam midsole. A decoupled rubber outsole yields reduced weight alongside data-informed traction.
