I also had a very painful Morton's neuropathy years ago; custom orthotics relieved the pain, but after I retired and was no longer wearing dress shoes to work the orthotics didn't fit. I wore shoes like NB for years with no problem but eventually the neuroma flared up again. New DPM simply recommended shoe with good cushioning and a wide toe. Went for a second opinion and that DPM put a strategically placed metarsal pad on the underside of the shoe insole to raise the arch. Solved the problem. Patch probably cost less than $10.
