So the supportive and cushioned shoes help reduce this impact, but it is still there.

By walking in minimalist shoes, or barefoot, I find that I really pay attention to how I walk and therefore walk better (normally slower). There are several benefits to barefoot walking, but you have to be listening to your body. Heel striking barefoot on concrete would hurt after a while.
