The F50 TUNIT technology gives football players the possibility to individually determine the feel and customise the performance of their shoes. Both according to the conditions during a game and according to their personal playing style. The shoe comes with three sets of studs: short studs for hard ground, normal studs for firm ground and the long studs for soft ground. The chassis can be switched around between “light weight”, “comfort” and “performance”. The uppers can be also exchanged to suit the player. The studs, uppers and chassis’ can all be purchased separately. This feature makes it easy to repair and upgrade the boots.
