The Aries x PUMA Mostro 'Mahogany Teak' features a hairy brown suede on the upper, secured with traditional laces in lieu of the original Mostro's adjustable strap closure. The signature Formstrip adorns the side panels in a textured design reminiscent of gills. Anchoring the sneaker is a spiked black rubber outsole and an iridescent midfoot shank.
