Hey Guy, Happy to hear you found comfortable shoes without having to spend so much on custom made
Is the nerve/ligiment problem a neuroma? The pod. I worked for used to inject steroid into them as well. Sometimes, if or when the steroid would not work, or stopped working he would have to do surgery to remove the neuroma (an area on the nerve that gets inflamed and causes scar tissue to grow and it is the tendon area that is effected there) something like that anyway.
Hope he helps you solve the pain issue. And mostly that the pain went away!
