1. A risk estimation apparatus comprising:
at least one memory configured to store instructions; and
at least one processor configured to execute the instructions to:
acquire measured data indicating a time variation of foot pressures of a left foot and a right foot obtained by sensors that are provided in shoes and measure the foot pressures;
identify a starting timing and an ending timing of a stance phase of each of the left foot and the right foot from the measured data of the time variations of the foot pressures;
estimate asymmetry between the foot pressures of the left foot and the right foot based on a local maximum value and a local minimum value of the measured data of the time variation of the foot pressures collected during the correspondence stance phase; and
estimate a risk of abnormality of a lower limb on the basis of the asymmetry.
