I’ve discovered the way to not have your arches collapse: lose weight!
You know that basic test to see what kind of foot you have- step on a dry surface w/ wet foot? shows normal, high, or flat foot? I used to show as completely flat, years ago.
My daughter was playing in the sprinkler last night, and wanted me to make footprints with her after my run. I took a look, and sure enough, I now have some arch (not a square block footprint). All it took was 30 + lbs of weight loss. Former lifter types, take hope and give it 3 years.
