A calcium deposit causing a protrusion on the underside of the heel bone is known as a heel spur. Heel spurs are typically linked to plantar fasciitis (when the ligament connecting the heel bone to the toes is strained, weakened, swollen or irritated). Heel spurs are the result of strains on foot muscles and ligaments, stretching of the plantar fascia and repeated tearing of the membrane that covers the heel bone. This is a common affliction of athletes who practice sports involving great amounts of running and jumping.
Heel spurs themselves do are not cause pain but rather the soft tissue injuries associated with them. People suffering with heel spurs will often feel as if a pin is sticking into the bottom of their feet when the first stand up in the morning. The pain will typically subside over time but can return after standing or sitting for prolonged periods.
This condition can result from a number of different factors. Causes of heel spurs can include: walking gait (an abnormality that places excessive stress on the heel bone, ligaments and nerves near the heel); running on hard surfaces; ill-fitting shoes (in particular those lacking proper arch support); and carrying excess weight.
Treatments for heel spurs can include stretching exercises and physical therapy; anti-inflammatory medications, cortisone injections and even surgery.
Heel spurs can easily be prevented and treated through the use of the Barefoot Science Strengthening System. The Barefoot Science insoles help to ease the tension and strain placed on the plantar fascia which heal the damaged tissues and prevent a recurrence of the problem. The insoles allow the arch to stabilize naturally, keeping the heel spur parallel to the ground, and less likely to protrude into surrounding tissue.
