This might be a bit of an odd question but I am trying to build something and trying to get as an exact answer as I can.

I am trying to build something for the bottom of custom carbon cycling shoes, a track per say for the bolts for cleats to bolt into, that way you could position the cleat anywhere on the bottom of your foot you preferred.

So the question I have is does anyone happen to know off hand how far the bolts holes are spaced apart from one another in a line that runs the direction of the foot and not a point a to point b line.

To further explain, if you were to bring the top bolt down and put it in a straight line with the two bottom bolts, what would that distance be between each bolt?
