How it works
A measurer - an employee of a company or a store - reads the article of a shoe model with a scanner, and then lowers a device that resembles a mechanical leg inside it. Its details begin to expand in the right directions, measuring the length, width, fullness of the foot, instep, softness of the insole, etc. Some parameters, for example the presence of laces, are specified manually by the measurer. At the end of the measurement, he presses a button on the smartphone, and the data goes to the cloud, where it is processed and entered into the database. Online stores integrate the Check Size widget into the site. When the buyer chooses a model, he enters the data: gender, size, type of foot - regular, full or narrow. The system calculates the length and girth of the foot and selects the models. If desired, a person can measure the length and girth on their own and make adjustments.
