Dressed in tonal Ghost Green, the Nike x Billie Eilish Jordan 1 KO capitalizes on the ongoing popularity of the versatile Jordan 1 silhouette. But there are a few subversions to this design.

Past that, the leather upper appears like canvas on first look thanks to stitched borders while a padded sidewall offers more subtle detailing. Billie Eilish’s logo sits on the tongue.
