Bally Leather Flexing Resistance Tester is used to determine the ability of a material to resist cracking or resist deflection at the bending crease. The test method is applicable to all materials, especially leather and coated fabrics for shoe uppers.

BALLY Water Penetration Tester is mainly used for the determination of water permeability and water absorption of shoe uppers. Mainly for the materials used in shoe uppers: leather, artificial leather, cloth, etc., cut standard test pieces, install them on the testing machine, and under the condition of water on the periphery, bend at a standard speed and angle, and bend for a certain period of time Measure the permeability index of the material as the basis for the research and development of improved material waterproof processing.
