An icon evolved. The Adizero 99g raced to the title of the lightest football boot in 2015. Four years later, we made it even better. Now, it's time for the next step. These limited-edition adidas boots take a comfortable lead over their rivals with a supple K-leather forefoot and the reinforced synthetic mesh quarter from 2019's X99.1. Underneath, an X Speedportal outsole ensures you're faster in all dimensions.
