Mine are UK size 8.5 and I do get the problem, I don't think that extra 0.5 makes any difference, more likely the driving position you adopt. My left foot catches the column i.e. not my brake foot (as Johnboy posted).
It does feel a bit strange when it happens as my foot gets moved the opposite way I am steering. This is because my foot is touching the bottom of the column. After it happended a few times I got used to it it, but I can imagine it being a bit more worrying if your braking foot was moved out the way as you come up to a sharp bend.
