MAESER TESTER
The uppers of shoes get folded over the toe portion every time a step is taken. These repeated folding cause the finished grains to start cracking, resulting in loss of water resistance. To ensure that the shoe uppers retain their water resistance for a reasonable period of use, the action of such folding on them is evaluated by subjecting test specimens taken from the material used for their manufacture to a water penetration resistance test. One of the methods used for determination of resistance of materials for shoe uppers to penetration of water through them due to flexing is based on Maeser test.
