The adidas Ultra Boost 4.0 'Triple Black' was released in January 2018, showcasing a sleek all-black design throughout, from the Primeknit upper to the energy-boosting midsole. What sets this edition apart is the midfoot cage, which deviates from the usual molded construction and instead features nylon material. To maintain the blackout look, the heel stabilizer is accessorized with tonal Ultra Boost branding. It's a performance runner that doesn't compromise on style.
