Many people report that a walking cast is the most helpful of nonsurgical treatments for plantar fasciitis (including rest, ice, heel cups, or cushions) they have tried.¹

Having your foot in a cast for several weeks causes some weakening of the foot, ankle, and calf muscles and some loss of flexibility. After the cast is removed, you will need some rehabilitation to restore strength and range of motion. However, a cast forces you to rest your foot, which is very helpful for relieving plantar fasciitis.

Casting is somewhat more expensive and inconvenient than other nonsurgical treatments. However, if other, less expensive treatments are not helpful, you often will have many more doctor visits, which add to the overall cost.

A removable cast (CAM walker) can also be effective, but you must wear it 22 to 23 hours per day.
