Experience all-day comfort with PowerStep Original innersoles, ...Worn maybe 3 weeks, the arch is too high and it does not work for my flat feet. These were recommended by my podiatrist, but they just don't work. They fit men's 6-6.5 or ladies 8-8.5. I don't have the box so I can't return them. They are compatible to the ones at the podiatrist, that are $100.
