JJJJound gives PUMA’s futuristic Mostro runner a stealthy makeover, cloaking its bold silhouette in deep navy suede and tonal detailing for a refined, minimalist update.

This collab features a rich suede upper in Deep Navy, complemented by a dot‑matrix suede Formstrip and off-white leather sockliner that subtly enhance texture and depth. JJJJound’s branding appears discreetly on the heel tab. Beneath, the Mostro’s signature spiked rubber outsole grounds the design in its original performance roots.

Despite its minimalist aesthetic, the Mostro retains its athletic DNA—built for grip and responsiveness. The padded interior, grippy outsole, and secure lace closure make it equally functional for urban exploration and everyday flexibility.

The Europe drop took place on June 14, 2025, with a broader release in the U.S. arriving on July 12, 2025, both priced at $160 / €160.
