adidas Originals have just returned with their Tubular X this cold season in a reliable ‘Solid Grey‘ repetition. A mottled black-and-white Primeknit platform forms the base layer across the entire forefoot, which then combines with a neoprene sock fit around the ankle (held together with the definitive X-shaped overlay in pebbled leather) and duo-tone white and translucent grey Tubular sole unit completes the sturdy sneaker.
