The Palace x adidas UltraBoost 21 'Black Multicolor' delivers the London skate brand’s sustainable take on the performance running shoe. A plaid pattern in white, yellow, red and green embellishes a black Primeknit upper made in part with Parley Ocean Plastic. Palace's Mobius recycling logo adorns the tongue, while an UltraBoost wordmark is embossed on the semi-translucent TPU heel counter. Responsive cushioning comes courtesy of a full-length Boost midsole, inscribed with 'Palace' on the lateral sidewall and supported by a Continental rubber outsole.
