What should I be looking for when trying out running shoes? Local store lets me try the shoe and jog up and down the block, but they mostly feel the same to me. Is there some feeling or anything else specific I should be looking for?

IT does not matter, mainly because it does not exist.

A belief in a god is not the problem.
