adidas‘s UltraBOOST continues to be one of the most coveted sneakers on the market. For those looking to switch things up, the UltraBOOST Uncaged is a great alternative. Losing its protective Three Stripes cage overlay for a more sleek slip-on look, the latest iteration takes on a new “Mystery Red” colorway. The Primeknit gradient features a navy-colored look on the toebox with the Three Stripes branding nearly camouflaged on the medial side. The adidas UltraBOOST Uncaged “Mystery Red” is available now at adidas’s UK online store for £130 GBP (approximately $164 USD).
