Its high-speed looks do not lie. This ultralight boot is built for extreme acceleration. A TPU bottom frame and new TRAXIONTM stud shape shed weight but not speed and agility. Upper: TPU bottom frame reinforces the upper and prevents abrasion in the kicking area. Singmax—a newly developed high-density nonwoven PU synthetic. Lining: All linings inside the shoe are treated with AgION technology, which works against bacterial growth and odor development. Inlay: A pre-molded sockliner offers maximum comfort and extra cushioning. Outsole: A new TRAXIONTM stud shape for maximum acceleration and grip on firm natural grass surfaces.
