# Spiked Mule Sneakers A$AP Rocky x PUMA Mostro Mule Arrives in Two Bold Colourways By Amy Duong | Published 2026-05-21 | Fashion Source: Trend Hunter, https://www.trendhunter.com/trends/mostro-mule References: [puma](http://puma.com/)  The A$AP Rocky x [PUMA Mostro](https://www.trendhunter.com/trends/puma-mostro-1) Mule is a laceless reinterpretation of the [PUMA Mostro silhouette](https://www.trendhunter.com/trends/mostro-cage), redesigned as a [slip-on mule](https://www.trendhunter.com/trends/air-jordan-mule) with an aggressive spiked rubber upper. The shoe is constructed from a molded TPU-like material with raised spike detailing across the toe, side panels, and heel, creating a sculptural, textured surface. It arrives in two colourways, black and a blue gradient finish, both emphasizing the same exaggerated, futuristic form. ([turn0search4]) The design removes traditional lacing and heel structure, replacing it with an open-back mule construction for easy slip-on wear. The outsole continues the Mostro’s signature spiked tread pattern, extending the visual language from upper to sole for a continuous sculpted effect. The upper includes perforated sections between spikes to balance structure and breathability.
