Description
New for Spring 2026, the B30 Countdown Tech sneaker is distinguished by its sporty silhouette combining couture codes with technical performance. Directly inspired by the modern running world, the ultralightweight sneaker is crafted in gray and green N3O nylon, a multilayer semi-transparent and ultra-breathable technical fabric. It is enhanced by gray injected rubber inserts, as well as a revisited CD30 signature in a graphic style. It also features rubber Dior B30 and CD30 signatures on the tongue and back. A sculpted sole in a blend of flexible rubber and foam ensures optimal comfort and is embellished with various hallmark details. The B30 Countdown Tech sneaker will complete both sportswear and casual outfits.
