Welcome @rannr, I think all of us folks with neuropathy struggle with balance and exercise is key to improving our quality of life. Here are a couple of balance articles from the Foundation of Peripheral Neuropathy:

-- Alternative Therapies That Enhance Balance: https://www.foundationforpn.org/brain-based-balance-exercises/
-- Maintaining Balance: https://www.foundationforpn.org/maintaining-balance/

Here's a YouTube video that I thought was helpful to understanding the challenges and what to work on. I like that it points out that certain types of shoes may cause more balance problems for people with neuropathy. - Standing Balance for People with Peripheral Neuropathy: https://www.youtube.com/watch?v=j1bjDmmpPkw
