Left foot big toe feels tingly, just the tip and bottom. I have been wearing flats and wide toed supportive shoes. I don't run but walk a lot.?

Nerve issues. tingling is a nerve problem. It could be coming from anywhere from your big toe up to your lower back. Locally, the nerve could be irritated at the big toe joint by how you walk even wearing the shoes you stated. It also could be a sciatic problem from your lower back. If it gets worse, have it checked. .
