Stiletto Sneakers

This topic is about the force and pressure.

If you mean the force exerted on the ground and considering only the heel of the needle relative to the whole of a shoe, then I calculate ~ 216:1. It is called a cure stylus is 1 cm ^ 2 (0.5 cm ^ 2 vs each) 216 cm ^ 2 for sneakers. We have done such a class, once the extreme is actually a higher ratio, while the minimum is a little less well than average. extreme difference is based on a larger shoe with everything being on average (which is unlikely, because the more pressure is exerted through the ball, toes, and heal a foot). minimum difference is based on the pressure of the foot contact area vs. total surface area of the pen, and the average is a cross between the two.
Anyway, if you have a 120 lb. woman, she is acting 120lbs/cm ^ 2 on the surface of the stilettos and 0.5555555lbs/cm only ^ 2 of the sneakers in this example. I guess the wisdom here is not trampled by a woman in high heels, but a woman in sneakers can be good (depending on your point of view). Oh, and this example is in a static evaluation (ie, immobile). If you consider the solution of the dynamic nature of the force of the stylus can be greatly increased due to the forces of movement and low, and the fact that both feet are not always on the ground). The ratio of dynamic solution is the same, but the actual pressure can be a multiple of the previous answer.

It is several times less pressure. The weight is distributed over the entire foot. The exact amount depends on how much space square is touching the ground with spikes.
