At 63 yrs. old, I had a year long peroneal tendon issue that I thought had become chronic. I had tried everything including  PT, exercises, rest, lots of ice and anti- inflammatories... I bought these thinking they'd be comfortable around my house and a light exercise shoe to pack on trips. Incredibly, within a month of wearing them religiously...in the house, outside doing ranch chores and on walks on and off pavement, the foot pain ceased. Now I've bought another pair in a different color.  I'm forever grateful!
