They are narrow fitting (not the best for wide feet) They provide very aggressive traction (great grip as you run) They offer a large ball striking surface (easy to strike the ball well) The X 19 are very responsive (they react well to your movements) 1 is built for players who love a thin and extremely barefoot speed boot experience. And that to me, is what's most exciting about the X Ghosted. 1. Yes it's a good boot, with probably the best outsole in recent years, but it isn't perfect, with areas for improvement such as the upper. Read full adidas x reviews click here thank you.
