What are the differences between the foot's dorsal and plantar surfaces?

The foot's dorsal surface is the top part of the foot, while the plantar surface is the bottom part. The dorsal surface is where the toes and the top of the foot are located, while the plantar surface is where the sole of the foot is. The dorsal surface is typically smoother and has less contact with the ground, while the plantar surface is rougher and is in direct contact with the ground when walking.
