Celebrating the fast foot chain’s century in business, the White Castle x PUMA Future Rider ‘100th Anniversary’ features a unique design inspired by the eatery’s signature square sliders. The upper is crafted from white textile with blue nylon paneling and a tonal leather Formstrip. White Castle branding adorns the exposed foam tongue, while a yellow ‘5¢’ tab is affixed to the sneaker’s lateral side. Mismatched graphics on each heel overlay is accompanied by text that reads ‘Buy ‘em by the sack’ and ‘A legend in a bun.’ Underfoot, PUMA’s Federbein outsole is rendered in a royal blue finish.
