Well the idea of running barefoot is that you run the correct way so your knees have low impact. When running with regular shoes you slam down on the back cause that's the only place you can, this put alot of impact on your entire leg. But when you run with these your foot is able to fall on the balls of your feet allowing for your foot, ankle, and leg to share the impact. Think of it as a spring. I am not trained as an ortho or anything I've just been researching this a lot, so please take what I say with a grain of salt. The shoe has three levels of padding Higher the number the more the padding. To help you adjust to the new experience.
