Similar to past UltraBoost collaborations with Beyoncé’s athleisure brand, the Ivy Park x adidas UltraBoost OG ‘Night Marine’ pairs refreshed details with a monochromatic palette. Varying shades of blue are applied to the sock-like Primeknit upper, secured with a toggle lacing system and fortified with a TPU midfoot cage. Atop the suede-covered heel counter, traditional UltraBoost branding is replaced by a debossed Ivy Park logo. The sneaker rides on a matching navy Boost midsole, supported underfoot by a Stretchweb Continental rubber outsole.
