I would suggest to you to take your Metanx on an empty stomach. B12 is not easily absorbed properly in the presence of food (particularly fiber).

Also one thing strikes me about your introductory post.
I would look to lacing those shoes too tightly. This can compress the nerves which are at the top of the instep of each foot.

I found this information and made a post about it.

This affects me considerably now that I am older. Compression can hurt!

There are other things as well, like insulin resistance(pre-diabetes), etc. But if you don't have symptoms in your hands and only the feet, I'd look at mechanical compressions first.
