Abstract:
An apparatus for measuring the moisture vapor transmission rate of a shoe, comprising:a hollow body made of self-supporting material, which reproduces the shape of a foot and is adapted to support the shoe to be tested, said body being adapted for containing water and having through holes which are distributed thereon for allowing water contained in the body to flow through the through holes; a sock made of waterproof and vapor-permeable material, arranged about the hollow body so as to enclose said hollow body; a presser configured to perform relative movements with said hollow body between a configuration in which the presser is spaced from a sole of the shoe supported by the hollow body enclosed within the sock and a configuration in which the presser is compressed against the sole of the shoe supported by the hollow body enclosed within the sock; a conditioner configured to heat water contained in said hollow body to a preset and constant temperature; and a device configured to weigh the hollow body, with the sock associated therewith, and the shoe to be tested; wherein the sock is almost entirely made of nonstretch material except for a region which corresponds to an upper part of the foot, which is made of elastic material in order to allow fitting over said hollow body, and wherein regions joining various parts of the sock are sealed in order to prevent the passage of water.
