“These boots are made for walking, and that’s just what they’ll do. One of these days, these boots will walk on over you.” This is a popular Nancy Sinatra refrain from the 1960s. It reminds us that footwear has been a part of civilization since time immemorial, when we first left the Rift Valley. (1) Of course, we did not have any covering for our feet. It was soon realized, however, that some form of protection made the journey forward and the hunting of prey far easier. Thus, the first undertaking of footwear was associated with self-transportation. Later, its significance was further amplified by the discovery that speed could increase one’s food supply. Foot coverings protected us from stones, thorns, and broken ground, allowing the body to move further and faster with far less injury.
