Heel spurs are a calcium deposit that causes a bony protrusion under the heel bone, caused by strains on foot muscles and ligaments or the repeated tearing of the membrane that covers the heel bone. They are often associated with Plantar Fasciitis, where the Plantar Fascia, or the band of connective tissue that runs from the heel to the ball of the foot, is inflamed.
Heel spurs can be treated with exercise or anti-inflammatory medications as well as cortisone shots in some cases. Sometimes a simple heel pad is sufficient for additional comfort.
Most heel spur pads and cushions are designed with a donut shaped area where the heel spur is located. The middle of the insert can be removed or there is an area with additional padding for relief.
