Shoe Flex Tester

The Shoe Flex Tester is used for determination of the ability of the full shoe to withstand the effect of flexing stresses produced on the different parts of the shoe. Although the various parts like uppers and soles of a shoe are tested separately for flexing endurance with the help of flexometer and Ross flex tester, the shoe flex tester gives results, which are more related to the actual performance of the shoe as a whole.
The Shoe Flex Tester simulates the effect of actual walking action on the shoe. The test specimen is held rigidly at the toe portion using a suitable toe last and clamp, while the heel portion has a separate last on which the shoe is firmly tied as in actual use.
The upper end of the sslast has an arrangement to connect a suitable link mechanism. The link mechanism is connected to an eccentric pin on a rotating block to give the link a to-and-fro movement. Both the eccentricity of the pin in the block and the length of the link are adjustable.
