The Air Jordan 4 Flyknit is debuting in 2019 in celebration of the silhouette's 30th anniversary. Four colorways will be offered and it will come in tonal iterations of Hyper Royal/Hyper Royal-Black, University Red/University Red-Black, Volt/Volt-Black, and Total Orange/Total Orange-Gunsmoke-Total Orange, all just in time for summer. This rendition of the silhouette follows last year's AJ 3 Flyknit to celebrate its 30th anniversary as well. Each shoe is simply constructed of Flyknit uppers and detailed with matching translucent plastic overlays on the wings and heel. Finishing touches include tonal Jumpman branding on the tongues, heels and outsole.
