Football boots have been waiting a long time to reach two digits. Now, after years of research, experimentation and testing, the arrival of the adizero f50 99GRAM marks the realisation of a dream. Weighing over a third less than the standard f50, the 99g edition is the lightest boot ever produced. You’ll have to show your speed to secure a pair of the groundbreaking boots; created as a strictly limited collection, only 299 pairs are available worldwide.
