Although bipedalism incurs disadvantages, these are far outweighed by advantages. The most important advantage is that upright posture is energy efficient and allows the hands to be used for other important tasks, such as carrying or building things with tools. The disadvantages of bipedalism include slow speed and strain placed on a body that was not intentionally designed to walk upright. Many of the problems arise from the fact that the weight of the body puts an incredible strain on anything below it, which means that organs and bones that normally had very little strain put on them now had to carry the weight of everything above it. The heart, for example, which normally rested on the posterior mediastinum, a structure in the chest, came to push against the diaphragm. To deal with this problem, the pericardium attached itself to the diaphragm, which allowed the heart to move with the diaphragm, as opposed to being pushed by it. The body has adapted to deal with many other mechanical issues, but it is not perfect, and, with aging, the effects of weight strain take their toll..
I haven't done anything quite so heinous as damaging the way of life of another living being on any without footwear functions yet.
