Human feet have metatarsophalangeal joints connecting the toes to the rest of the foot. But humanoid robots don't have these (at least, the vast majority don't). Why? These joints are very useful.
Also, the bottom of the human foot is soft and has thousands of nerve endings. Can we really expect robots to get anywhere near human mobility performance without this level of compliance and sensory sophistication?
