First released in 1999, the Mostro has become one of PUMA's best-selling shoes ever. Affectionately named after the Italian word for "monster," it was originally inspired by two sports shoes – a sprinting spike from 1968 and a surfing shoe from the '80s. With the Mostro Fey, we combine its signature bold design with a delicate Mary Jane silhouette and a shiny satin upper for a look that's entirely new and undeniably PUMA.
