Can skeletal surface area predictin vivofoot surface area? [PDF]
Journal of Anatomy, 2019 AbstractThe surface area of feet in contact with the ground is a key morphological feature that influences animal locomotion. Underfoot pressures (and consequently stresses experienced by the foot), as well as stability of an animal during locomotion, depend on the size and shape of this area.
