I have suffered with what I think is mortons neuroma for a lot of years. I can just about manage it by being careful with my footwear. Exercise is difficult as once it is aggravated it won't go away for a few hours. I recently started Zumba and love it, but it is casing me problems. I have some good orthotic insoles which help and have tried vionic, skechers and Nike trainers. But still getting problems. Has anyone any specific recommendations that are not too expensive.
