For Over Two Decades It’S Been Worn By Those Who Defy Conventions And Eschew The Norm. Taking Its Name From The Italian Word For Monster, Mostro Is A Hybrid Creation That Draws From Two Diverse Realms: The Sleek Sprinting Spikes Of The ‘60S And The Surfing Shoes Of The ‘80S. To This Day It Continues To Captivate With Its Distinctive, Sculptural Design, Low-Profile Shape, And Avant-Garde, Spiked Sole.
