Summary:

• The hips, knees, heels and toes help us to walk more efficiently (use less energy).
• Pelvic rotation reduces the downward motion of the CG through the contact pose.
• Pelvic list reduces the upward motion of the CG through the passing position.
• Knee flexion of the weight-bearing leg also keeps CG lower in the passing position.
• Heel and toes increase and decrease the effective length of the leg.
