Vamp Leather Flexing Tester is used to determine the propensity for materials to crack or otherwise fail at flexing creases, but can also be used to assess whether leathers are likely to produce salt spue. The method is applicable to all flexible materials and in particular those used to manufacture outers and linings of footwear uppers such as leathers, coated fabrics and textiles. The test can be conducted with either wet or dry specimens at room temperature. In particular the test simulates conditions in the vamp part of footwear during walking.
