Do insoles for heel pain relief work for nurses?

I've been in nursing for almost 20 years and know tool well of the agonizing pain that comes after doing a 12 hour shift. To answer your question, insoles can help but what really made a difference for me were custom orthotics. They are molded to your feet so they cushion the spots that hurt the most and give proper arch support. I can actually get through my shifts without that constant ache at the end.
