Mostro is a true fusion of sport and lifestyle. It first released in 1999 and has since become one of PUMA's best-ever selling shoes. Affectionately named after the Italian word for "monster" and originally inspired by two sports shoes – a sprinting spike from 1968 and a surfing shoe from the 80's – the Mostro is well-known for its signature closure system and low-profile spiked sole. Today PUMA bring it back in a more aggressive iteration with slightly longer spikes on the sole.
