Nike Mercurial Victory IV IC - Boys' Grade SchoolYou might have thought the Mercurial was as fast as it could be. Unfortunately for defenders, you were wrong. The Mercurial Victory IV is back, with even more lightweight speed. The soft, synthetic leather upper is designed to give players increased ball feel. The contoured last mirrors your foot's natural shape while a contoured sockliner and textile top cloth add low-profile cushioning. Underneath, a non-marking, tinted gum rubber outsole brings its innovative Vapor traction pattern to the indoor court. Wt. 6.4 oz.
