I was going to say the CrocRx, too. My mom bought some, unfortunately she passed away before she got to wear them, so I guess I will wear them, I have plantar fasciitis and they are good for that too.
Make sure you get the Silver Cloud.
Also her doctor suggested New Balance. If she can tolerate them, Birkenstocks are great for Diabetics, too. Try a website for a company called Footsmart, they have many, many options and great prices, and free shipping. That is where I ordered moms Silver Cloud
Crocs, they will send you a catalogue that have some great choices.
