PUMA and JJJJound reunite to bring the Montreal-based studio's unique touch to the cutting-edge PUMA Mostro, a low-profile silhouette named after the Italian word for "monster" that borrows from two diverse realms: the streamlined sprinting spikes of the 1960s and the surfing shoes of the 1980s. Arriving in two muted colorways, the PUMA x JJJJound Mostro features a premium leather and suede build alongside a stitched PUMA Formstrip on the sidewall above a signature spiked rubber sole. Distinct JJJJound branding hits the heel counter to finish the minimal design. PUMA Mostro x JJJJound Leather and suede upper Regular fit Lace closure Embroidered detailing Spiked rubber sole
