Green equals style. It's a simple equation really. As a base tone, green gives a boot energy and life. When used as an accent, it gives it a snarl! Being one of the most natural colours, green lends itself to a nice balance between style and self-expression. While not as loud as some of the other tones, green still makes a statement, but does so with class.
If the pitch isn't too muddy and still has some grass, then perhaps you'll get a camouflage effect with your green boots disappearing before the eyes of the opposition?! Perhaps not..
