It has just "clicked" in the last few weeks! Dr. Seuss would be proud!
But if you look at this picture (I am almost barfing that I'm posting it), you might be able to tell what my right-footed boy spends most of his waking hours doing. (HINT: Involves a black and white ball, and at school, a muddy field).
If you can't see it, the entire right big toe side of the shoe is blowing out. Lots of kicking, I guess!
And if it's not soccer, it's this...
