The Jordan Why Not Zer0.4 ‘KB3 PF is a highly breathable shoe that represents the fourth signature shoe of Russell Westbrook. The sneaker features a slate blue mesh upper, complemented by lavender webbing straps that are seamlessly integrated into the lacing system to provide a secure and locked-down fit. The shoe also offers excellent responsiveness and cushioning, thanks to the double-stacked Air Zoom units located in the forefoot of the full-length foam midsole. Specifically designed for the Asian market, this PF version includes an extra-durable rubber outsole that is perfect for outdoor court play.
