Puma Mostro JJJJound Deep Navy - In collaboration with JJJJound, these Puma shoes arrive in two eye-catching colorways: Dark Chocolate and Deep Navy. Both versions take PUMA's spiked silhouette and add JJJJound's signature laid-back style. The sneaker's upper is made entirely of suede, while the Formstrip gives it a futuristic feel without being flashy. JJJJound keeps a low profile, placing their name discreetly on the heel tab.
