adidas F50 adiZero TRX FG Leather - Men'sIt's one of the planet's fastest boots. It owes its light weight to leather with SprintWeb stability, a Sprint Frame outsole, and a new stud shape. But like any great soccer cleat, the performance is in the details. The full-grain leather upper includes a Goleo calf leather vamp for a snug, light fit. It's supported by SprintWeb technology for quicker cuts and dribbling stability. The TPU bottom frame reinforces the upper and prevents kicking-area abrasions. Inside the shoe is an ultralight sockliner. In addition, the Sprint Frame construction of the outsole uses geometry for stability. The F50's new TraXion® stud shape is designed 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. Wt. 7.2 oz.
