<P> The Predator Precision introduced replaceable Traxion studs that were fitted by the tightening of a minute screw . These studs were available in various lengths that made the boot adjustable to ground conditions as is possible with the classic screw - in soft - ground studs . There were, however, some reliability problems, as the studs would come loose quite often, thus needing more constant maintenance than the classic screw - ins . In 2001 came a completely revised model which had a similar stripe configuration and colourway but the predator technology was revised and bore more of a resemblance to Predator Accelerators . </P> <P> Controversy arose over the boot's ball - directing striped - line zone in 2002 when Hungarian football gear inventor László Oroszi launched a copyright lawsuit against Adidas . Oroszi had registered the patent in Hungary in 1996, explaining that the striped zone at the tip of the shoe permitted footballers to shoot more accurately . Oroszi's representative presented the patent to Adidas in 1998, but Adidas declined the offer claiming that it did not fit into their concept for the then new Predator Precision shoes . Eventually in 2014, the Hungarian Courts ruled that Adidas had incorporated Oroszi's deisgn into their Predator Precision shoes and that he is entitled to compensation . </P> <P> Adidas released the Predator Mania to coincide with the 2002 FIFA World Cup in South Korea and Japan . They designed it with a "Far Eastern" style in mind, so it had sharp angular styling and came in various colour schemes in addition to the traditional black--red design . These included the "champagne", a champagne - white colour, and the "champagne gold", a gold pearl - like white, although just stud background and heel cup was gold . These were worn by David Beckham, Alessandro Del Piero and Raúl . These were available in the XTRX Blades for soft ground use, which came with a stud key and could be loosened or tightened at the owners comfort and also the red firm ground blades for hard surfaces . These were not detachable and came fixated to the boot . A limited edition version was also released in "Japan Blue" and was worn by Alex of the Japan national team during the tournament . During the 2002--03 playing season, they also released an all - red version with the Adidas stripes in silver . </P> <P> Problems with reliability of the XTRX Blades meant a revised version was released in late 2003, which incorporated minor changes to the layout and design of the studs . In addition to this, with the revision, Adidas also released the boots with traditional screw in studs which were previously only available to professional players who had the boots custom designed by Adidas . Two new colours were released: "lunar", which came out in March 2003, and "gun metal", which was released in time for the 2003--04 playing season . The final revision of this boot came with the release of the HG (Hard Ground) sole, which was the same as the FG, except that the studs were black instead of red and were joined up and more robust with the boots intended to be used on third generation and synthetic surfaces . "Blue Mania" were only released in small numbers, primarily in the North American market, Japan and Korea; they are rare in Europe . </P>

When do the new adidas predators come out
