Sidi shoes

I have 2 pairs of Sidis, Dominators for commuting and Genius for track/road, and both are the same size, 47. It felt a bit short at first, but length-wise they are perfect now. The only issue I'm having is that when wearing the road shoes I am getting a feeling of discomfort, which leads to pain, just to the left of the ball of my foot. Is this more likely to be a cleat position issue or one with the shoe itself?

The road shoes, again unlike the MTB versions, seem to allow a bit of lateral movement of my feet, which makes me think my feet must be very narrow indeed.

Most likely cleat position, not the shoes
