I'm having trouble with the adjective "dorsal", as different authorities have seemingly conflicting opinions.
Tortora and Derrickson write in Principles of Anatomy and Physiology that the adjective for things pertaining to the upper surface of the foot is dorsal. They also claim:
Posterior (dorsal): Nearer to or at the back of the body. [...] The terms posterior and dorsal mean the same thing in humans
- relating to or situated near or on the back especially of an animal or of one of its parts
- situated out of or directed away from the axis
- (anatomy) With respect to, or concerning the side in which the backbone is located, or the analogous side of an invertebrate.
- An anatomical term referring to the top surface of either foot and/or hand.
What does the word mean?
