I wear 10.5 US size shoe, and prefer XL toe clips, though my toes are longer than normal. I used to use L, but found that going deeper in the toe clip alleviated some pain/cramping on the outside of my foot. You need to determine how long you need to get the ball of your foot over the spindle. For your size foot I would probably start with L. Somewhere there are measurements showing the length of various sizes.
