A$AP Rocky x Puma Mostro Mule Releases May 21

A$AP Rocky and Puma are expanding their collaborative footwear vision with the Mostro Mule, a backless reinterpretation of the brand's experimental 3.D. silhouette designed for warmer-weather versatility. The slip-on arrives May 21 in Blue Glimmer and black colorways, each priced at $250.

The partnership between the Harlem artist and the German sportswear house continues to push the brand toward more daring, fashion-forward territory. The Mostro Mule strips away the heel of its predecessor—introduced last September—while preserving the sculptural construction and aggressive outsole geometry that defined the original's character. The result is a shoe that maintains experimental DNA while trading intensity for ease of wear.

Two colorways will launch simultaneously. The first, "Blue Glimmer," features a gradient treatment that shifts from blue to black across the upper, creating visual depth without visual noise. The second opts for a monochromatic black execution. Both styles are punctuated by red accents on the Puma branding, a restrained design choice that prevents either pair from veering into oversaturation.

Since joining forces with Puma, Rocky has positioned the brand's newer silhouettes within broader conversations about motorsport aesthetics, futuristic design language, and avant-garde streetwear function. The Mostro Mule represents another step in that trajectory—a shoe that exists comfortably between statement piece and practical lifestyle wear.
