The Undercover x Nike SFB Mountain is an innovative fashion creation by Japanese designer Jun Takashi, which offers a fresh take on military-inspired style. Inspired by Bill Bowerman's service in WWII, this particular model of the boot, known as the 'Obsidian Red' boot, was launched in April 2019. In this version, Takashi adds his own twist by incorporating a customized mesh upper with technical enhancements such as toggle laces, crisscrossing straps, and heat-welded overlays. Streetwear influences are also evident through co-branding elements, Swoosh logos, and text graphics. Built to withstand harsh conditions, the boot features a robust sole with aggressive traction, ideal for adventurous individuals with a rugged lifestyle.
