The Jordan Why Not Zer0.4 ‘KB3 PF showcases an airy build on Russell Westbrook’s fourth signature shoe. The sneaker makes use of a slate blue mesh upper, accented with lavender webbing straps integrated into the lacing system for a lockdown fit. Responsive cushioning arrives via double-stacked Air Zoom units nestled in the forefoot of the full-length foam midsole. This PF version is exclusive to the Asian market and features an extra-durable rubber outsole made for play on outdoor courts.
