I’m only 87, but have been running and then walking for most of my adult life. Here’s what I learned. No need to buy expensive shoes. Get reasonably priced ones (I love Dr Sholls from Walmart in leather for about $30. Very fashionable too.). THEN go to drug store(or Walmart) and buy insoles (preferably Dr Sholls again) for working and walking—nice thick gel ones. Trim to size and stuff them into your chosen shoes. Voila! Very comfortable thickly padded walking shoes. Some insoles are made to support arches etc. I have come to the point that I put these insoles into almost all my shoes! So comfortable!
