HOW HEAL PAIN DEVELOPS
If your foot pronates too much, the ankle rolls too far downward and inward with each step. This can cause the arch to collapse and muscles and supporting structures to over-stretch and lengthen. The ligaments running from the heel to the toes become strained, often leading to inflammation along the bottom of the foot. This inflammation and heel pain is known as plantar fasciitis. In response, the bone may also develop a bony growth (heel spur), right in the center of the heel. This too causes heel pain and can prevent an individual from walking with ease.
CAUSES OF HEEL PAIN
Injury, disease and excess weight are among the possible culprits, but it’s probable that your heel pain has developed from poor biomechanics.

You’re not alone, however. A majority of the American population experiences misalignment due to over-pronation. Over-pronation can become even more excessive when you wear unsupportive shoes and walk on hard, unnatural surfaces.
