Your foot is not designed to run on concrete
It's "designed" to run on anything, including hard surfaces. The difference between a hard surface like concrete and a soft surface like dirt is trivial.
What injures people is transient spikes of shock from bad form such as heel striking. These may be dulled by soft surfaces, but they're completely eliminated by good form, even on concrete.
I can't believe you're serious. ALL injuries are ELIMINATED by good form? You are a very, very ignorant person. I guess you just read Born To Run...?
A repetitive stress injury occurs when the stress applied to a tissue exceeds its tolerance. You can have the most perfect form and still get injured when you push the limits of your muscles, tendons, ligaments and bones. Running will ALWAYS cause stress to those tissues, and during recovery they will get stronger. But if you run more than those tissues are able to handle at the moment, you will get injured.
Injuries associated with forefoot striking are a bit different from injuries associated with heel striking. Forefoot strikers a more prone to foot, ankle and calf injuries, and heel strikers tend to get more shin, knee, hip and lower back injuries.
If you suddenly start running on a hard surface with no cushioning, your metatarsal bones WILL be stressed more than what they are used to, even if you run with a short forefoot strike. That's why metatarsal stress fractures are so common in VFF runners.
Don't get me wrong, I'm not against minimalist shoes of barefoot running and I've overcome some nasty chronic injuries by switching to minimalist shoes myself, so I definitely believe that a more natural way of running has benefits. But at the same time I get so frustrated in these stupid barefoot runners who make irrational claims like "you can't get injuried if you have a good form". WAKE UP!
