Social progress, economic development. Hundreds or even thousands of pairs of shoes can be seen everywhere for us, and can be seen in major shopping malls, but when people spend money, they also consider quality issues, which requires shoes to be tested.

Now, GESTER introduces from the Shoes Flexing Tester.

1. Application

Upper and Vamp Material Flexing Tester GT-KC04A 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. In particular the test simulates conditions in the vamp part of footwear during walking. The test can be conducted with either wet or dry specimens at room temperature. 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.
