My podiatrist asked me to bring in my trail footwear and shoes I wear frequently in everyday life. He looked at the trail shoe, boot, and casual every day shoes then told me to stay with the trail boot for a while but get a more sturdy casual shoe. I got a stiffer soled casual shoe and the problem disappeared in a few weeks not to return. Turns out it was the casual shoes that started the problem.
Sometimes it's not in the gear we use on the trail but the in-between gear we use that we don't pay as much attention to.
