Did you ever see the TV documentary on how Predator boots were developed?
It was an idea of Craig Johnston's (forh Liverpool player) and the original intention was for cheap footwear
Eventually when Adidas took the design, it was then marketed as a performance enhancing product so has been retailed at a premium
After retiring from playing football, Johnston found success as a businessman and innovator, designing and creating the prototype for Adidas' Predatorfootball boot, worn by many of the world's top players of both football and rugby including Zinedine Zidane, David Beckham, Steven Gerrard, Xavi, Jonny Wilkinson and Ronan O'Gara. He later designed another innovative boot called The Pig or, to give them their full title, the Patented Interactive Grip can come as a 'skin' that can be placed over the toe of an existing boot. Getting the first boot off the ground took Johnston 5 years and was initially refused by Adidas, as well as Nike and Reebok. However, Johnston had filmed Franz Beckenbauer using the boots in Germany in snowy conditions, and its increased grip led to Adidas agreeing to the proposal.
