These boots are made for walkin'

Okay, so it's only one boot not two and it's supposedly made for walking but sometimes I'm not so sure.  Of course I'm talking about my new best friend and boon companion: a handy, dandy cam-walker.  (the big, black, strappy boot thing I'm sure you've seen people walking around in).  It is delightful on a hot August day.  I've been wearing it for two weeks now and my heel STILL hurts just as bad as always.  They say six weeks in the boot should do the trick but I'm not so sure.  I've been consuming mass amounts of calcium foods and supplements to try to give my body a subtle hint that it is time to start making some BONE in my heel.  Knowing my luck I'll just end up giving myself a kidney stone and still have a stress fracture.
