The human foot has three arches, but the chimpanzee foot only has one.

Explanation: Humans have medial and lateral longitudinal arches plus a transverse arch that help support upright bipedal walking. Chimpanzee feet are more flat and grasping (with an opposable big toe) and lack the well-developed three-arch structure of the human foot.
