A digital mechanical measurement last comprises a three-dimensional tension-compression sensor, the center of the three-dimensional tension-compression sensor coincides with the mass center of the last, the long axis of the three-dimensional tension-compression sensor is parallel to the long axis of the last, two ends of the three-dimensional tension-compression sensor are connected to the front part and the rear part of the last, and circumference of the three-dimensional tension-compression sensor is not in contact with the last. The last helps a model designer to check and analyze problems existing in shoe models and materials, so as to improve timeliness and accuracy of model modification, save manpower, material resources and research and development time, and make shoe products fitter and more comfortable.
