I wear soft-sold barefoot shoes and get outside barefoot as often as possible. I feel like it does help me feel more relaxed and less anxious.

I've definitely heard of grounding but have tried it myself. I helped start an online group for people with MS and we discuss things like grounding and I heard only positive things. It was recommended soft soled shoes when not going barefoot. I go outside but stay in my wheelchair but have heard only good things
