It's all about sole

Let's take a comparatively minor modification of human behaviour -- the wearing of shoes.

People have been wearing shoes for a few millenia now. Has it been long enough for evolution to start de-selecting for hard-soled people and allowing in more sensitive footsies? Think about it. People with tough feet probably ran faster, longer, were a better survival bet. But with shoes, all that changes. No longer are sensitive-footed folk scorned as mates.

Now consider whether the genes controlling the sensitivity of feet also control other traits. Maybe tough-feeted people are also more resilient, less likely to suffer post traumatic stress and so on.

If this were true, then when women torture their feet by wearing stilettos, we're actually proving our "toughness".
