The 2025 reissue of the Undefeated x AJ 4revives one of the most coveted collaborations in sneaker history, originally released in 2005 in an ultra-limited run of just 72 pairs. Drawing inspiration from classic military flight jackets, the design fuses utilitarian aesthetics with the timeless craftsmanship of the AJ4.
Constructed from premium nubuck with molded eyelets, TPU support wings, and a co-branded heel tab, the silhouette captures the partnership’s bold identity. Velcro tongue patches, contrast lining, and visible Air cushioning complete the look — a perfect balance of heritage, exclusivity, and modern edge.
