My best friend gets it. It happens when her hip rotates forward and her spine is out of alignment. Then she gets pain and numbness all the way to her foot. I've given her massage, etc. seems to help for a while. Hope that info is helpful somehow.
I'm having a problem tripping over my left foot, the types. I bought some new sneakers yesterday, and I explained if been treated on my balance at Mayo. Mayo said when they tested me toes down I wasn't able to balance as well. She said I needed to wear shoes with an 8mm "offset" or less. She told me to Google "Offset" to understand it, and added Merrell shoes have great variety. I bought Saucony sneakers. 🙏🌼
