Did you know that God or Natural Selection made a mistake when Feet were created. The creator thought we would not stand up much but gave us feet just in case we had to briefly move. This is why we have such misformed feet with arches for no reason. Because if we walk a bit our arches are not strong enough and we will collapse them and die. God screwed up. But the Doctors put a solution to a problem you didn’t know you have and that god didn’t realize, into every shoe. An arch support. This fixes gods screw up and allows us to walk more than 10 seconds without breaking down our feet and die. Think long and hard about what I am talking about, Our feet and arches are built correctly, and strong and almost nobody ever needs shoes but for a but of foot protection. Arches are almost never an issue. But the arch in every shoe wrecks my feet and knees. The doctor says he will build some sort of orthotic arch to counter that arch but he says You must have arches in shoes. This of course makes no sense as I have explained. I was about to get knee and ankle operations. The only flat shoe is an open toe thong sandle. They don’t last long but that’s all I wear all the time and I have no foot or knee problems at all after 50 years of issues I figured it out. I run 25 K in these 3 dollar sandles and feel nothing. You do recall famous African distance runners who never wear shoes, imagine them in arched shoes. Most ladies prefer flat sandles as well. I double up putting one sandle on top of the other so they last really long and are more cushiony. Genius, the entire world can now walk, run and not screw up their feet, ankles and knees for just 3 bucks.
