In honor of the fast food chain's 100th anniversary, the White Castle x PUMA Future Rider '100th Anniversary' sneaker showcases an exclusive design that draws inspiration from the iconic square sliders served at the eatery. The upper is skillfully crafted from white textile, complemented by blue nylon paneling and a matching leather Formstrip. Notably, the exposed foam tongue proudly displays the White Castle branding, while a yellow '5¢' tab accents the sneaker's lateral side. The heel overlays feature mismatched graphics and bear the phrases 'Buy 'em by the sack' and 'A legend in a bun.' Completing the design, the PUMA Federbein outsole boasts a striking royal blue finish.
