adidas teamed up with famed chemical company BASF to create Boost technology. Said to withstand three times the temperature of traditional EVA materials, Boost soles became a go-to option for runners when launched in 2013. This UltraBoost 4.0 'Ash Grey' iteration debuted in March 2018 as a part of four colorways released by the Three Stripes brand. Constructed with an ultra-breathable Primeknit upper and cushioned Boost midsole, these runners provide comfort with every stride.
