Objective: To describe the anatomy and biomechanics of the foot and to
explain how movement and gait are integrated in the foot during walki
ng and running. Design: We review the anatomy and the biomechanical ad
aptations of the foot during walking and running. Material and Methods
: Illustrations are presented to depict these biomechanics. Results: T
he human foot is an intricate mechanism that cushions the body and ada
pts to uneven surfaces. It provides traction for movement, awareness o
f joint and body position for balance, and leverage for propulsion. Co
nclusion: With an understanding of the factors discussed herein, clini
cians will have more knowledge to evaluate foot problems.
