Hello, I'm trying to find every bit of research I can comparing the health of feet in habitually shoe-wearing and habitually barefoot cultures. Unfortunately, I only have two direct studies from years ago and one modern study on bones. Can anyone help lead me towards finding more? 
The studies I have are:
.Conclusions Drawn From a Comparative Study of Barefoot and Shoe-Wearing Peoples, ..The Journal of ..Bone & Joint Surgery. 1905; s2-3:105-136.
.
.
Survey in China and India of Feet That Have Never Worn Shoes
Shulman, Pod.D,, Samuel B. (1949) The Journal of the National Association of Chiropodists (Now known as the American Podiatric Medical Association).
Shod Vs Unshod: The Emergence of forefoot Pathology in Modern Humans?, B. Zipfel, L.R. Berger (2007)
