Nike Cortez Union Grey Blue
The Nike Cortez Union Grey Blue reimagines the classic Nike model through a collaboration with Union Los Angeles. This special edition transforms the historic silhouette with handcrafted details that give it an aged and authentic aesthetic.
The upper combines a vibrant striped canvas base with grey suede overlays that add texture and depth. Union details mark the cult boutique's signature style on the cork insole, forefoot, and tongue, while the eyelets and midsole feature a deliberately worn, patina-like appearance.
This contemporary interpretation features a speckled grey and black Crater midsole, a signature of the brand's sustainable craftsmanship. The Union collaboration brings its premium streetwear vision to the Cortez's running heritage, bridging the gap between past and present.
