Bracing a body part weakens that body part in the long run.
Anybody who has ever had a cast on their arm knows this firsthand.
Probably Vibram FiveFingers
Also: wearing them makes you understand that you wear gloves when everyone is stuck at mittens.

A lot of my problem also related to back pain when growing up, and I realized also in my 20's how much going to the gym helped with the back pain. As my back got stronger via strength training, I no longer suffered from back pain. Additionally I invested more in things like a good office chair at home and ensured I had a good one at work.
Overall I no longer have back problems and no longer require any inserts in my shoes.
About 20 years ago, I was riding my bike everywhere and hardly walking. I went on a trip to NYC and was walking 10+ miles a day. I developed severe shooting pains in my feet. Getting some supports helped dramatically and so I started wearing them whenever I wore shoes.
I did this for about 15 years and completely swore by arch supporting shoes. Then, one day I was playing basketball and landed on someone's foot going for a layup. My foot basically folded in half in the opposite direction of the arch. This was a major injury and I could not walk at all for a week and it took multiple years before I stopped feeling pain regularly in that foot.
After the injury, I completely stopped wearing arch supports. I had a theory that my feet had been weakened by using them and that this weakness was the underlying reason for the severity of my injury. For the last few years, I have averaged about eight miles of walking a day and mostly wear zero drop minimal shoes. I have developed the ability to run on concrete with them, though I do not particularly enjoy this (primarily because my running efficiency is poor).
If I were running a marathon, I would certainly wear shoes with padding, but I don't find much padding or support necessary or even desirable for brisk walking for hours at a time. And for almost 15 years, I never left the house without bulky supports.
