I have Morton’s toe which I think is different from Mortons Neuroma. I started getting pain in my second toe which eventually led to a metatarsal problem. I now have custom made orthotics with a small raised ridge in the upper section which has helped a lot. I found that wearing narrow shoes especially in the toe box aggravated the pain I had in my toe. So having a wide toe box could help. Your toes then have space to spread. Don’t wear tight socks either. Gentle toe stretches also help - scrunching your toes and then releasing. I hope you find a cure.
