For the first time in the Mercurial line, these boots incorporate a 3/4 length Zoom Air unit in the soleplate, designed to provide responsive cushioning and propulsion for explosive speed. The upper features Vaporposite+, a combination of grippy mesh and premium materials for an exceptional fit and enhanced ball control at high speed. An internal speed cage made of a thin but strong material helps secure the foot to the soleplate without adding bulk, ensuring a locked-down fit.
