Since its debut back in January, the adidas Ultra Boost has been gaining a lot of momentum in the sneaker community. Drawn to its technical innovations and ultra-clean aesthetic, collectors have been steadily adding it to their closets. Just in time for summer, the Three Stripes has unveiled a tonal grey colorway of the popular silhouette. Comfort and breathability are second nature to the design with its Primeknit upper, while the signature Torsion System provides added support. Completing the look is a white crepe sole and a black outsole. The silver adidas Ultra Boost is available now at select European retailers, including sivasdescalzo. Stay tuned for details on a stateside release.
