Change the game in the X Crazyfast+ FG Firm Ground Football Boots. Crafted to feel lighter than air, the boots have a semi-translucent Aeropacity Speedskin+ upper with reinforcements only where they're needed. Lightweight laces strap you in, while a SPEEDFRAME OUTSOLE with AEROPLATE is designed for propulsion & dynamic movement. We have reduced the carbon footprint of this pair of shoes by a minimum of 10% when compared to a previous version. Less greenhouse gas emissions, including CO2, for the full lifecycle — from creation all the way to end-of-life.
