As I said, I am up to 1/4 of a mile every other day. I plan to increase this distance verrry slowly. As of now, this feels great!
The NB 877 seem to be a good middle of the line. They are rated as a cushion shoe but are far more ridgid in the mid section than the Nikes I used to run in. I have gotten a custom orthotic back from my Podiatirst and have tried them in the 877's. The orthotics are like leather, not hard and not soft either. Right now, I plan to wear them everyday and run in them. This seems to be a good middle of the line. This gives fairly good cushioning and allows very litle pronation.
I wish you the best and hope you are able to get back to running without pain. Heck, I wish the same for myself. Let me know how you are doing and I will do the same.
