These are a fantastic upgrade from previous Mercurial boots. Right away you notice how much lighter they feel. The NikeSkin upper gives a much better touch on the ball, and the fit is snug without feeling restrictive. The Dynamic Fit collar keeps your foot locked in, and the traction has been great! Overall, they feel faster, more responsive, and more comfortable than my last pair. Definitely a worthwhile upgrade for anyone looking for a lightweight, speed-focused boot
