During standing, the foot must bear the body weight with a minimum of muscle energy expenditure. In addition, the foot must be either pliable or relatively rigid depending on various functional demands, such as adapting to absorb forces and accommodating to uneven surfaces or serving as a structural lever to propel the body forward during walking and running.
