The present invention discloses a digital mechanical measurement last, which specifically comprises a last, a three-dimensional strain gauge load cell, a signal amplifier, a data acquisition card, data acquisition system software, and a data line. After a shoe upper surface is sleeved over the digital mechanical measurement last, forces applied on the last by the shoe upper surface are transferred to the three-dimensional strain gauge load cell through a front part of the last and a rear part of the last, so that the three-dimensional strain gauge load cell is strained, which causes a change in a resistance value of the three-dimensional strain gauge load cell, thereby generating a voltage change; the voltage change is processed by the signal amplifier; the data acquisition card transmits data to a PC in which the data acquisition system software is installed over the data line and through a USB interface; the data acquisition system software records, displays, performs computation on, and analyzes signals, which 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.
