THE SCIENCE OF SPEEDConstructed from synthetic, the Nike Mercurial Victory VI football boots feature embossed ridges on the upper, while its tongueless construction provides a locked-down fit. A perforated sockliner and synthetic top cloth inside the boot mirrors the natural shape of your foot to reduce stud pressure. A full-length compressed TPU outsole with conical and chevron shaped studs offer durability and traction on artificial grass surfaces.
