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 Mesh Upper.
