The "feet" picture.  Kinda scary, I know.  Those are feet that are pretty much beat to hell by too many years and miles and miles in various "running shoes".  That name should be outlawed in the first place.  The "heel stompers" that you can buy from countless outlets unnaturally confine your feet, unnaturally cushion your heels to the point that you don't run the way your feet were DESIGNED to run.  The rubber, gel, goo, foam pillows under your heels prevent your feet from experiencing the joy of the run.  You consequently plod along, heel, toe, heel, toe, heel, toe.  In my opinion, and it is just that, everyone should dump those things unless you have some real medical reason to wear them.  Run like you were made to run.  I personally prefer to run in huaraches.  Little more than a piece of rubber out sole laced to your foot with some cord.  If you haven't tried it, you won't believe it.  Start slow,  just a little ways to let your feet live again.  Gradually increase your distance.  I usually run between 3 and 5 miles most days, and have had NO damage, blisters, etc. since I started wearing them.  I got them from InviibleShoe.com., a company which I consider a pioneer in the minimalist running gear arena.  Their link is on the right side of this page under "Useful Links".  Take a look at it.  They have TONS of useful information there.
