The mechanism for our body movement is done with the aid of our legs, the weight of the whole body resting on our feet. It allows us to stand, walk, run, climb and numerous other activities.
In a very different twist we are the only species that needs specialized addition to our body, from clothes to shoes. Unlike other animals who have developed fur from their skin, and pads for their feet, we haven’t. We improvised and used natures resources to aid us in the environment.
Shoes provide the right grip for our feet in relation to our environment, there are instances where specialized shoes are needed for each environment. Each terrain differs and humans have been able to utilize the natural resource from nature to make shoes that fit the body and the surrounding.
Design of shoes has varied enormously through time and from culture to culture, with appearance originally being tied to function. Some shoes are designed for specific purposes, such as boots designed specifically for mountaineering or skiing.
Usually shoes have been made from leather, wood or canvas, but with the advent of new technology they are increasingly made from rubber, plastics, and other petrochemical-derived materials.
While shoe making was done in most of our history by hands, we have developed sophisticated tools that aid in creating such products. With ever more complex machines such products are now being built in large numbers with ever more design options.
