- The horizontal plane of the forefoot is perpendicular to the bisection of the calcaneus.
- There is a minimum 10° ankle dorsiflexion.
- Leg must be vertical to the ground in frontal plane.
- Leg must be vertical to the ground in sagittal plane.
- There is no horizontal plane rotation in limb above.
