The Jordan Why Not Zer0.3 ‘KB3’ features a design that honors Russell Westbrook’s late best friend, Khelcey Barrs III. In addition to a woven KB3 patch stitched onto the lateral side, Russ’ third signature shoe is dressed in contrasting tan and green hues that recall camouflage print – a symbolic nod to how the two friends were always ready to go to war for each other. Performance benefits include an Air Zoom Turbo unit in the forefoot and a flexible split rubber outsole.
