The NB I have read about are the 990,2002, and the 1500 models. I hope you have good luck with them. I don’t personally wear tennis shoes. They seem to aggravate my neuropathy. I was told that SAS were good also, so I bought a pair of flats for summer, and am very happy with them, although I did have to ‘break’ them in because of my bunions.

Before you buy any NB be sure you try them on. It is also important to get a shoe with a roomy toe box. You don't want a shoe that is tight around your toes. I have been wearing NB for years. My ortho doc highly recommended them when I was a nurse. The best for someone who was on her feet for many hours. Now with the PN, I find these are still the best for my whole foot.
