I wouldn't recommend barefoot running shoes unless you are running on soft surfaces. I am a provider who specializes in orthopedics and rehabilitation, specifically orthotics and prosthetics at a university hospital.
Our clinic is mainly patient care oriented, but we do get to do some research. The barefoot running fad was kicked off by from what I believe to be a purposely clumsy interpretation of some really interesting studies.
Mostly an investigative study about the bio mechanics of tribes in Africa who traditionally ran long distances without foot wear. The study is actually really great, but a lot of the proclaimed benefits aren't really applicable to other environments or cultures.
These tribes had their runners training without shoes at a very young age, and always on soft surfaces. If you take away any of the preconditions and the benefits also disappear.
