I haven't had any issues with my cambon flats and was literally able to wear mine right out of the store. I shopped all afternoon while wearing my brand new cambon flats and not once did the flats hurt my feet.
Okay I just got the Cambon flats today and although they are a lot cutier than I originally thought they fit wierd. I got the 36 which is my size generally and my heel slips on the left and on my right the front presses down on my big toe. They feel kinda stiff will they give in time? Is it worth keeping and stretching out the right and putting the no slip cushions from Nordies on the backs?
