You're talking millimeters at most. Probably enough to not worry about.
Basically you can measure the thickness of most cycling shoes from the
outside, since they're not constructed with a welt typically, and pull
out the insoles and measure the thickness of those. Add and compare.

John,
There isn't a really good way to do it just yet. Be that as it may, I
place the shoe on the pedal and measure the whole distance from the
center of the spindle to the top edge of the sole.
I do this by holding a mm ruler lined up with the center of the pedal
spindle, then pressing my thumb along the top edge of the sole. Where
you feel the edge, there lies the sole. While the aboolute numbers you
obtain are of questionable accuracy, by repeating a few times you should
be able to get a good idea of the difference between the two, which is
what is important. Clearly this doesn't account for differences in the
footbed curvature among shoe models.
Of course, changing shoes and pedal systems can make differences that
are far larger in magnitude. The difference between my road shoe/pedal
and mt. shoe/pedal is a whopping 17mm!
Best,

(disclaimer: we sell bike fitting tools, so I have a vested interest in
the opinion that shoe thickness matters. However, that opinion was
among the many that *led* to my professional involvement, rather than
the other way around :-)
