A new series of high-tech football boots with reduced weight and high-contrast colours has been unveiled by Nike.

The launch of the Mercurial Vapor Superfly II, CTR360 Maestri, Total90 Laser III and Tiempo Legend III boots comes just weeks before the beginning of the 2010 World Cup finals in South Africa.

Nike said the new boots had had their weights reduced by the use of modern carbon fibre materials, and used high-contrast purple and orange colours to enable players to spot their team-mates on the pitch.

All boots will be available through the normal retail channels and online from 22 May.
