Running barefoot forces you to improve your technique in line with this description. [0] There's also a sizeable market of "barefoot shoes" that's between being barefoot and the regular running shoes, with the manufacturers trying to convince us buying such shoes is the solution. The gait issue become more obvious (and painful) in barefoot shoes, but you can adjust your technique in mass-market running shoes as well.

I first found out about this back when Chris McDougall's "Born to Run" book came out. For anyone that does not know, he follows an Indian tribe in Mexico known for their running prowess, using non-traditional sandles to run in instead of the heavily padded sneakers most of us wear.

I switched briefly around that time to running in vibram five fingers, which trained me how to change my stride and stop heel striking. I no longer wear VFFs but do tend to favor lightweight, minimal heel-drop sneakers, and I still don't heel strike.

I'm not sure you can run with appropriate gait (stop heel striking) in modern mass market running shoes. The heels on many running shoes are 2 inches+ and make it just impossible to avoid heel striking without wasting a lot of motion picking your knees up.

Also, the chances of twisting your ankle when your heels are elevated that much from the road is far higher as well.
