Sports doctors, podiatrists, and even evolutionary scientists are jumping into the barefoot running debate.
As the running barefoot trend continues to gain momentum, the questions over the benefits and handicaps continue to grow as well.
Pro-barefoot scientists state that running shoeless lets runners run on the padded part of the foot versus the heel.
A barefooter's steps are springier and use their calves and feet muscles better.
Evolutionary scientists are also studying how hunters could survive with no shoes for millions of years.
Shod runners' feet are protected and shoes offer performances advantages.
Shoes can also offer more ankle support while bare feet offer flexibility.
Also, shoe companies are rebranding and creating "minimalist" shoes to cash in on the the barefoot craze.
