The hugely popular Mercurial is bringing the speed again in the Miracle III FG. But this isn't any Mercurial. This cleat is the newest addition to Cristiano Ronaldo's signature line. The lightweight Teijin synthetic leather upper gives the best in ball feel, conforming to your foot shape for natural touch and support. The new contoured speed last delivers superior fit and a complete lockdown. This gives a track spike-like fit that remains snug. In addition, the low profile toe box makes it easier to get underneath the ball on those long shots. Zonal reinforcements in the medial and lateral sides. The perforated sockliner with synthetic top cloth mirrors your natural foot shape to reduce stud pressure. Also inspired by track runners, the forefoot grip zone provides traction during those extra bursts of speed. The TPU outsole uses two layers of glass fiber composition to help transfer energy into the sharp, direct-inject blades. This gets your plant foot quickly in and out of placement for consistent acceleration. The cleats are positioned in an asymmetric Vapor traction pattern that aids in changes in direction. The midfoot speed stud adds support to this high-pressure zone, especially during full-speed sprints. Two heel studs are placed to prevent grass build-up and optimize stable field penetration.
