I recieved a set of these and a single tab from a sports therapist after suffering from plantar fasciitis for nearly a decade. I've spent thousands over the years searching for relief. These insoles did it.
Combined with the soft as clouds cushion of my Hokas, I can be on my feet all day on my days off with zero heel pain!
Unfortunately, they don't fit in my issued work boots due to my high instep, and by dinner time, I can barely walk, and still have 12 plus hours left in my shift! Next time the fire department buys boots, I'll be taking these with me to make sure my new boots accommodate them!
