My husband has suffered with painful feet for years. He's tried specialty shoes, orthotics, multiple doctor visits, and was considering surgery. These gave him the variety to wear throughout the day and through the night, comfortably. They don't require special shoes or uncomfortable/awkward design. Now he is walking and standing comfortably with a lot less issue and seeing a visible improvement in his feet and toe contour.
Almost instant relief. These are great to wear around house.
