You DO NOT want your cleats to force your feet to point in a un-natural position.
The latest thinking concerning where the spindle position is this. The spindle should lie between your 1st and 5th metatarsal. This is normally about 2.5mm behind the ball of your foot. With your foot in your shoe you should be able to squeeze the sides enough to feel where the boney protrusion is that will mark the ball.
BINGO!
This photo is from Andy Pruitt's book, and he recommends you not look down while a friend measures the angle of your natural foot position relative to fore-and-aft. The easiest way to do this is using a goniometer. Attach the cleats to your shoes at the same angle your feet naturally assume with your legs dangling off the table top.
Goniometers are cheap ($5 to $10) and available at medical supply stores.
