The adidas Ultra Boost 2021 “Triple White” is a monochromatic white colorway of the comfortable running and lifestyle shoe by adidas. New for 2021, the Ultra Boost 2021 progresses the design of the popular low-top by featuring the model’s largest Boost cushioned midsole at the time of its release. Increasing in size as it curves toward the heel, the white Boost midsole sits beneath a white eco-friendly Primeblue woven upper constructed from environmentally conscious materials. A tonal Three Stripes midfoot “cage” assists in supporting the lacing system and a white molded heel counter secures the wearer’s foot in place. Small perforations on the toe and mid-panel allow for constant airflow to the foot. Underneath, a semi-translucent Continental Rubber outsole completes the look. | UltraBOOST 2021 Cloud White.
