Undefeated teamed up with adidas for a unique take on the UltraBoost in spring 2018. Undefeated applied its simple yet bold aesthetic to the modern classic running silhouette. The upper is all black with a high-contrast “UNDEFEATED” logo that starts on the midfoot of the right shoe and ends on the left shoe. The Undefeated “bars” insignia is also incorporated into the sneaker's tongue. The Undefeated x adidas UltraBoost was another great addition to the California retailer’s impressive list of sneaker collaborations.
