Known as the Battle Grey colorway, just like the Nike Basketball Collection, this Air Jordan 31 features a grey textured upper that shows wear and tear, or that has been “battle-tested.” Nike says that this colorway of the 31 “represents the challenges Jordan Brand athletes— age in some cases, inexperience in others — and their teams — particularly complacency and doubt — face at the beginning of a new campaign. United, these athletes play to overcome critical tests and prove naysayers wrong.”
