We've designed and developed the Training Ball for young footballers who have just joined a club or who play occasionally. Too light? Too heavy? The weight is standardised! Between 410 and 450g (Size 5)Between 350 and 390g (Size 4) How about you? What do you think? We value your feedback and use it to continuously improve our products. A huge thank you in advance for sharing your feedback with us. Optimal sphericity for a precise bounce! We analyse the ball's sphericity at 4500 different points and then measure any discrepancies. The average variation must be no more than 1.8% (in accordance with FIFA BASIC rules). If the ball goes beyond this threshold, our engineers intervene to optimise its shape and guarantee an even, precise bounce with every kick! The ultimate resistance test: the machine shot test The most demanding test that this ball is subjected to is the machine shot test. The ball must resist up to 2500 shots against an inclined flat concrete slab at 50 km/h at a distance o
