Definitions

  • the present invention refers to a system for measuring the comfort of footwear in general, and in particular of made-to-measure (customised) shoes.
  • Known to the art for this purpose are systems for the choice of made-to-measure shoes, which comprise a scanner that performs a measurement of the morphology of the foot and returns data indicating the geometric shape of said foot. These data are processed by a special software and used to identify, among those present, a library of known lasts, or to create a customised last (comparable to the mould of the foot). This last is used to create a made-to-measure shoe that derives from the last that is selected or created starting from the geometric data of the foot acquired with the scanner.
  • a dedicated software creates and manages a database that matches the different foot shapes to the lasts of the respective shoes.
  • Object of the present invention is to overcome the drawbacks of the prior art, by providing a system for an objective measurement of the comfort that is precise, accurate, versatile and able to aid the choice of a made-to-measure shoe such as to ensure, by its nature, the maximum comfort for the user.
  • the objective comfort measuring system comprises a sock adapted to be worn on a foot and an item of footwear to be tested. Said sock or said item of footwear or both are provided with measuring means adapted to measure the distance and/or the pressure between the foot on which the sock is worn and the item of footwear.
  • the data indicating the distances and/or the pressures measured are processed by a software programme so as to provide useful information for the selection of the ideal last for a made-to-measure shoe.
