Shoes make the man, or in this case, the athlete. This study shows that shoes (much like skis) allow us to perform faster than our brain is able to compensate ( in other words, we lack the skill) and allow us to sometimes stretch our abilities, often at the cost of an injury. We must remember that technology must keep pace with the rate of neural learning, not the opposite.
