Iliotibial Band Syndrome is the result of poor training habits, equipment and anatomical abnormalities.

Training habits:

• Running on a banked surface (such as the shoulder of a road or an indoor track) bends the downhill leg slightly inward and causes extreme stretching of the band against the femur
• Inadequate warm-up or cool-down
• Increasing distance too quickly or excessive downhill running
• In cycling, having the feet “toed-in” to an excessive angle
• Running up and down stairs

Abnormalities in leg/feet anatomy:

• High or low arches
• Overpronation of the foot
• The force at the knee when the foot strikes
• Uneven leg length
• Bowlegs or tightness about the iliotibial band.
  • Excessive wear on the outside heel edge of a running shoe (compared to the inside) is one common indicator of bowleggedness for runners.

Muscle Imbalance:

• Weak hip abductor muscles
