I reckon it's either that the lengths of the arms on your crank spider aren't all the same - so a manufacturing fault which shouldn't be likely on those miches - or it's your peddling* motion that is pushing the chain off line, maybe try tightening your cleats/straps?
*that's as in turning the pedals not hawking goods ;-)
