I had a dx from a podiatrist in 2006. He tried various iterations of inserts, they only helped some. What helped the most was switching my brand of shoes. I now wear mostly Birkenstock, Keen's, and Stegman's clogs (for indoor shoes in the winter). I no longer use inserts and haven't since the first year of dx. I have to be careful with some Keen's as not all styles accommodate my bunions, but they usually provide enough support. House slippers never provided the needed support so I only wear in the evening when I'm winding down for bed.
Good luck - that Morton Neuroma pain can be an issue that limits activity!
