Somewhat related, for years and years I've walked a lot (average is 4-5 miles a day, every day). About 5 years ago I started having pain in the ball of my feet and I couldn't walk much. I was about to give up, when I discovered MBTs, which are a "rocker" style shoe. It saved me. Now, I have 4 pairs that I rotate and I have many fewer issues. They gave me a scare a few years ago when they declared bankruptcy, but they came back a couple of years ago. I believe I have Morton's neuroma, and it makes sense that a rocker-style shoe would help this malady. Regarding the article, I don't know why some of these people can't just buy two pairs of shoes of different sizes and just use the correct shoe from each pair for each foot.
