An expandable platform for measuring plantar pressures includes a multiplicity of modules (1) for measuring plantar pressures, each having mutually orthogonal sides and including its own array of sensors able to measure plantar pressure, and a control computer provided with a software for the treatment of the information coming from the sensors, able to display the static, postural and dynamic examination of the plantar pressures. The array of plantar sensors of each module (1) is connected with the control computer through an interface (2) positioned inferiorly to the measuring module (1) in such a way that each measuring module (1) is individually connectable for the transmission of data with the control computer, and is electronically and mechanically joined to other measuring modules (1) positioned adjacent to its own mutually orthogonal sides.
