My suggestion is to break it in real easy. Your going to go through two/three weeks of extreme discomfort but it will pay off in the long run.

My problem was always with my knees. I didn't go through the normal wearing in time with my shoes and ended up blowing out a knee cap. Lovely.

I think the problem is that wearing the shoes more than your supposed to will end up in a collasped arch once you suddenly take your shoes off at the end of the shift. It's not that you'll break a bone Miss Emily but that you'll do tons of dammage to the ligaments. Ligament recovery can take a year to a year and a half (don't ask me how I klnow this).
