In July 2017, Puma collaborated with the Lower East Side sneaker store, Extra Butter, to release the exquisite Extra Butter x Clyde 'Kings of New York' sneaker as a homage to the relentless hustlers of New York City. This special edition of the iconic Puma Clyde showcases a luscious Cabernet crushed velvet upper, accompanied by matching velvet laces and a tonal leather formstrip. The eyestay features gold foil branding, while the tongue and heel incorporate veg tan leather. Additionally, the leather insole displays co-branding, and the outsoles are transparent, revealing an asymmetrical 'Extra Butter' logo.
