Just a word for those whose shoes hurt. You can stretch them out yourself by cramming the toe box with paper/socks/anything to fill out the space. Leave them for a few days and put the padding back in after you've used them. This helps ease the tightness of wearing a close-fitting shoe.
If the heel box hurts you you can be a bit more aggressive by pounding a bit with a hammer. Yes, I know it sounds brutal, but it some cases you will never wear down the hard heel box unless you take matters into your own hands. I don't get blisters, and my feet are more important to me than any shoe.
