I had that with the Chambers with old style atacs and the platformed mx4(I think?).
Gave up on the shoes in the end, they were too flexy and could never get them to feel right regardless of pedal type...
I have mx4s on another bike and find them to be more supportive actually, just can't use the Chambers to ride my fixed as that's got the old style atacs.
