Modeled after one of the planet's fastest boots and powered by the legendary Lionel Messi. The F10 uses a synthetic upper with asymmetrical lacing for a larger kicking surface. Inside the shoe is a die-cut EVA insole for lightweight comfort. All linings inside the shoe are treated with AgION antimicrobial technology to work against bacteria and odor. In addition, the F10's TraXion® 2.0 stud shape has a new triangular design for maximum acceleration on firm, natural surfaces. Adult sizes are miCoach compatible, so with the reduced weight, you'll find out just how fast you can be.
