Artificial Ground Boots - It's the players you can't predict who change the game. The ones who pull chances out of nowhere. Who can't be caught because their opponents never know what they're going to do next. The creative playmakers who are always unmistakable and always unpredictable. The X15.1 is the men's football boot for that player. It has a flexible adidas Primeknit upper for quick moves into and out of the box and the NON STOP GRIP (NSG) texture that keeps the ball where you need it.
