Tibiotalar and subtalar kinematics were measured in vivo using dual-fluoroscopy.
- class="label">•
1 and 3 DOF models were used to predict hindfoot kinematics from skin-marker data.
- class="label">•
Joint angles predicted by models were compared directly to dual-fluoroscopy data.
- class="label">•
Both models predicted trends in hindfoot joint angles, but not discrete values.

Our results underscore the importance of appropriate selection of kinematic models.
