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. For those who dare to be bold, this latest version has a somewhat more aggressive look with slightly longer spikes and a contemporary take on camouflage.
