The Puma x San San Gear Mostro Cage is a collaboration with the culture-based lifestyle apparel brand San San Gear. This iteration draws inspiration from fast-paced Korean street culture, particularly the delivery drivers active at night. The design features a suede upper with textile underlays and an asymmetric construction. It replaces the traditional forefoot strap with a quick lacing system, utilizing a webbing lace system with a disc closure for a secure fit. The embroidered Puma Formstrip is present across the upper, and the shoe is finished with Puma's signature spike-detailed rubber outsole for traction and visual impact. Collaborative branding appears on the heel and insole, with a soft TPU heel overlay featuring the Puma Cat logo.
