Shoe Shank Stiffness Testing Machine
Category：Footwear Strength Tester
Introduction
This Shoe Shank Stiffness Testing Machine evaluates the thermal insulation and moisture permeability performance of the entire shoe by measuring its heat retention, moisture absorption, and breathability, and tests it together with long socks.
The test takes into account the effects of the sole, upper, and lining, as well as the influence of stitching and various types of socks.
Application
1. Footwear Manufacturers: Optimize the combination of upper/sole materials (e.g., mesh fabric, breathable leather, thermal insulation cotton) during the R&D phase, and conduct random inspections of product breathability/thermal insulation consistency during the production process;
2. Outdoor/Functional Footwear Sector: Test the breathability and moisture-wicking capabilities of athletic shoes, hiking boots, and safety shoes, or the thermal insulation performance of snow boots and cold-weather boots, to match the demands of outdoor scenarios;
3. Quality Inspection and Compliance: Conduct breathability/thermal insulation performance testing of footwear products according to standards such as GB/T 3903.14 and ISO 20344 to ensure that products comply with industry standards;
4. Brand Quality Control: Verify the authenticity of the breathability/thermal insulation indicators advertised for products to enhance product competitiveness in the market.

FAQ
(1) What is this product?
A Shoe Shank Stiffness Tester is a laboratory testing device used to measure the longitudinal bending resistance and structural rigidity of the shank (the reinforcement between the heel and ball) in shoes.
(2) What is this product used for?
A Shoe Shank Stiffness Tester measures the longitudinal stiffness and flexural rigidity of shank components (steel, wood, or fiber) used in the arch/waist region of shoes.
(3) How does this product work?
A Shoe Shank Stiffness Tester measures the longitudinal bending resistance of the shank (reinforcement strip) in the waist of a shoe. It works by clamping the heel end, applying a downward load at the front end (simulating heel strike), and measuring the deflection to calculate flexural rigidity.
(4) Why is this product important?
A Shoe Shank Stiffness Tester is crucial for ensuring footwear safety, stability, and comfort by measuring the rigidity of the shank—the “backbone” between the heel and ball of the foot. It verifies that shoes (especially high heels and work boots) maintain shape, prevent ankle injuries, and provide proper arch support.
(5) Which industries is this product suitable for?
A Shoe Shank Stiffness Tester is primarily used in the footwear manufacturing, component supply, and quality inspection industries to measure the longitudinal stiffness of shank reinforcements in shoes. It ensures structural integrity for men’s, women’s, and children’s footwear, especially for high-heeled or safety shoes.
