Y-3 x Adidas Adizero Adios Pro 4 Competition Running Sneaker KI6875

Y-3 x Adidas Adizero Adios Pro 4 — Where World Records Meet Yohji Yamamoto

The Y-3 x Adidas Adizero Adios Pro 4 is one of the most compelling collaborations in performance footwear — a shoe that exists at the precise intersection of elite marathon technology and Yohji Yamamoto’s uncompromising design philosophy. The Adizero Adios Pro 4 is Adidas’ most advanced competition marathon shoe, engineered to break records on the world’s most demanding courses. In Y-3’s hands, that performance architecture becomes something else entirely: a design object that carries its speed credentials with the quiet authority of a Yamamoto garment. Style KI6875 is the result — a shoe that runs at the front of the pack and stands apart from the crowd.

Design Heritage

Y-3, the long-running collaboration between Adidas and Yohji Yamamoto, has always operated on the premise that performance and aesthetics are not opposing forces — they are complementary ones. The Adizero Adios Pro lineage represents Adidas’ most serious commitment to marathon performance, having paced some of the fastest times in road racing history. When Y-3 applies its design language to that platform, the result is a shoe that honors both traditions without diluting either: the carbon fiber energy rods are still there; the LIGHTSTRIKE PRO foam is still there; and so is the unmistakable Yamamoto sensibility that makes every Y-3 product immediately recognizable.

Key Features

• Upper: Lightweight engineered mesh with Y-3 design detailing for breathability, structure, and a refined aesthetic distinct from the standard Adios Pro
• Midsole: LIGHTSTRIKE PRO ultra-lightweight foam for maximum energy return and race-day responsiveness
• Energy Rods: Five carbon-infused Energyrods 2.0 that mimic the metatarsal bones of the foot for a natural, propulsive toe-off
• Heel: LIGHTSTRIKE cushioning in the heel for additional impact absorption and a smooth heel-to-toe transition
• Outsole: Continental™ Rubber outsole for reliable grip on road surfaces in wet and dry conditions
• Fit: Sock-like upper construction for a locked-in, performance fit with minimal material bulk
• Weight: Race-weight construction — engineered for speed without sacrificing structural integrity
• Design: Y-3 signature aesthetic detailing — Yohji Yamamoto’s design language applied to Adidas’ most advanced marathon platform

Why the Y-3 x Adizero Adios Pro 4?

There are collaboration shoes, and then there are collaborations that make sense. The Y-3 x Adizero Adios Pro 4 is the latter — because Yohji Yamamoto has never been interested in putting his name on something that doesn’t deserve it. The Adios Pro 4 deserves it. The LIGHTSTRIKE PRO foam, the Energyrods 2.0, the Continental™ rubber outsole — this is a shoe built to win marathons, wearing a design language built to endure. Style KI6875 is for those who understand that the fastest shoe in the world is also, in Y-3’s hands, one of the most considered. Run in it. Wear it. Either way, it’s the right choice.
