So first you need some shoes and/or inserts designed to let the PF heal. I have had great success with Vionics. Expensive but the relief is worth every penny. Avoid buying on QVC as their made for QVC versions are less expensive for a reason. A good department store (Dillard’s) or Amazon are better sources. A good running shoe store will have suggestions as well for other brands.
Spring break sales for flights are already going on. Enjoy your tours!
