Agreed. I think you should be able to go to either extreme that is safe. 1. Everyone gets just the equipment they were born with. Its barefoot with nothing beyond basic clothes for modesty/support. In this scenario its all about the human body and training. 2. The other end is springy shoes, aerodynamic clothing. 3. Farther down the line you have safe technology like 100% O2, autologous blood tranfusions. Nothing that permanently changes the body. If you think some of these things are dangerous, I'd counter that the sport itself is dangerous and well known for its injuries. 3a. Even farther you have the things that can cause permanent changes/death for the athelete. EPO, steroids, Perfluorocarbons etc.
