Air Jordan 4 Retro OG SP Undefeated (2025)

Model heritage and Undefeated code

The Air Jordan 4 Retro OG SP Undefeated (2025) returns to the military aesthetic that gave the "fours" a raw character in a limited interpretation from years ago. Tinker Hatfield's AJ4 silhouette remains untouched: mesh panel, eyelet wings, and distinct sole geometry. The SP (special project) designation signals refined details and selective distribution, typical of special projects.

Palette and materials – olive meets safety orange

The upper is made of soft nubuck in an olive green shade, paired with black inserts and safety orange accents on the tongue and inside the collar. Matte wings, mesh panels, and lacquered TPU elements create a layered, tactical look. Tonal stitching and precise edges emphasize the quality of craftsmanship, and the whole maintains a clear, military palette.

Construction and characteristic details of AJ4

The padded tongue with exposed foam refers to the archival specifics of the model, and plastic eyelets stabilize the lacing during intense use. Subtle, cooperative branding complements the Jumpman, without dominating the design. Perforations and the mesh panel support breathability without losing the structure of the upper.

Cushioning and everyday fit

The midsole combines resilient foam with a visible Air unit in the heel, and encapsulated cushioning works under the forefoot for a smooth stride. The classic tread of the rubber sole provides traction on urban surfaces. The balanced height of the upper stabilizes the ankle, maintaining comfort for all-day wear.
