Optimized simulations of AL-288-1 walking erect with either human-like or chimp-like mass distribution always produce deeper heel than forefoot impressions, making heel contact first
Optimized simulations of AL-288-1 walking bent-hip, bent-knee with either human-like or chimp-like mass distribution always produce deeper forefoot than heel impressions due to ankle dorsiflexion, making contact with the full foot.
