Heel Pain
Purchase:
PowerStep ProTech, Full Length Inserts. (You might find them online OR my office has these in stock and you can purchase at the front counter for $60/pair; these will hurt if you do not gradually break them in. Start with only 1 hour per day and add an hour per day with standing/walking. Once you can tolerate walking in them all day long, you can exercise in them also. They typically last 1 year.
Night Splint. Find on Amazon for ~$25 (get the one that looks like a boot, not a sock).
If you wear sandals, consider these brands that have a built-in arch: Oofos, Vionics, Birkenstocks or Chaco’s.
*Best shoe recs: Asics or Brooks (should not be flexible through the shoe sole).
