This is a weird one. about 18 months ago I went to a running shop and went through their gate analysis. I've attached an image of the results, which mention "overpronation". However, my shoes always wear down on the outside, not the inside (image attached), and this website says that signifies supination: https://www.runningwarehouse.com/learningcenter/gear_guides/footwear/pronation.html
I've attached an image of an old shoe of mine so you can see.
What is happening here?
