If having duck wide feet wasn't problem enough, my parents decided (with he help of shyster shoe salesmen) to save me from flat feet. Remember fluoroscopes in shoe stores in the early 50s? Consequently, I wore orthpedic shoes during my formative years and now have arches like the Lupu Bridge. Of course, not only do I now have to look for wide shoes, but I have to buy arch supports or my feet are in pain after a few weeks. So no, orthotics and arch supports are definitely not a scam.
Those old leather/cardboard Dr Scholls supports were pretty bad, but they were better than nothing, in my case. Finally, I ran across Spenco brand and they saved my life. Great design and last for damn near forever. I've been wearing the same inserts for over 15 yrs. Since then, I've seen many orthotic improvements come on the market and in many cases they WILL save you from much pain and back grief. Your feet are not to be taken lightly. They support your whole damn body, fercryinoutloud! ;)
