PUMA's Mostro Fey offers an understated take on the Mary Jane-inspired sub-lineage. The sleek leather upper features tonal Formstrips and secure hook-and-loop closures, while OrthoLite sockliners ensure comfort. The design is completed with spiked rubber outsoles, characteristic of premillennial sprinting spikes, providing futuristic grip. This model ties the bold aesthetic of the Mostro with a Mary Jane silhouette, retaining the distinctive spike-soled design while updating the uppers with an elastic hook-and-loop closure. The low-profile leather upper is presented in white with Cat motifs on the heels. Comfort-focused OrthoLite footbeds are supported by rubber soles.
