In September 2018, adidas commemorated the Seoul Summer Olympics' 30th anniversary by introducing the UltraBoost Clima 'Seoul 1988.' These running shoes pay tribute to the historic games by incorporating elements from previous UltraBoost models while also incorporating a South Korea-inspired twist. The breathable Primeknit upper, Boost midsole, and a unique design featuring alternating red and blue heel counters, black stripes along the white midfoot caging, and a yin-yang symbol on the tongue evoke nostalgic memories of the host country in 1988.
