Do we need to change shoes used for running or walking after 6 months or 300 miles? I've read this and seen frequent mentions, and also heard it from a triathlete and marathon running relative. If not replaced in a timely manner scary things are supposed to happen.
It seems kind of wasteful, and I can't find any reliable sources of studies done. The shoes I use now have a lot of miles, I'm adding >1K per year, can't find a replacement pair to fit my misshapen feet, and wonder what others do. Lots of runners here, so I ask is this a clever marketing ploy by shoe manufacturers or a sound practice for healthy feet?
