+1 Every Shimano shoe I've ever had has this hole for ventilation.
As for the knees, it could be from an incorrect seat height or fore/aft position. Your toes pointing inward or outward should be a matter of how your legs are built (bow legged, knock kneed, rotated hips, whatever), and forcing them to an unnatural position usually isn't a good idea.
