Understanding Types Of Shoe Flexing Tester

Shoe flexing tester is a vital piece of testing equipment in footwear manufacturing and quality‑control laboratories that helps to evaluate flex‑resistance performance of shoes. When it works in good condition, your footwear products can go through reliable durability testing and prevent defective footwear from reaching end‑users.

You’re about to discover what shoe flexing tester is and the different types of shoe flexing tester used in the footwear industry.

Destructive Flex Testing

As the name suggests, destructive flex testing will produce visible damage to the shoe or component being tested. It is the most effective way to determine the flex fatigue limits of shoe materials and bonded seams. Destructive flex testing is essential to discover real‑world failure characteristics of soles, upper fabrics and adhesive joints.

Non‑Destructive Flex Evaluation

Non‑destructive flex evaluation seeks to find early‑stage defects in footwear samples without fully breaking down the specimen. This process does not completely ruin the shoe, but it identifies subtle flaws like tiny incipient cracks or weak bonding, allowing you to assess whether the shoe can hold up for its intended service life.

In effect, non‑destructive flex evaluation helps verify material and assembly quality and, therefore, the quality of the final finished footwear product.

The SATRA TM92 Whole Shoes Flexing Tester GT-KA01-2 is designed to evaluate the flexing durability of complete footwear by repeatedly bending the shoe and checking for cracks or damage. It is suitable for sports shoes, safety shoes, work shoes and other footwear products. The tester complies with SATRA TM92, ISO 24266 and HG/T 2871, and features touch screen control, adjustable bending angles up to 90°, preset test cycles and automatic stopping.

The SATRA TM161 Sole Flexing Testing Machine GT-KB06 evaluates the flexing resistance of footwear soles by repeatedly bending sole specimens and measuring crack growth. It is designed according to SATRA TM161, ISO 17707, ISO 20344, ISO 20347 and related footwear standards. The machine provides a 90° bending angle, 125–150 CPM flexing speed and 3- or 6-station configurations.

The ROSS Flexing Tester GT-KB05A is designed to evaluate the crack resistance of rubber, PU, PVC, TPR and other flexible sole materials under repeated bending. It is commonly used for footwear sole and rubber material testing according to ASTM D1052, SATRA TM60, BS 5131:2.1, ISO 5423 and ISO 4643. The tester uses a standard ROSS flexing mechanism with repeated bending and stable specimen clamping.

The Bally Resistance Flexing Tester GT-KC10A is used to evaluate the flexing durability of leather, synthetic leather, coated fabrics and other flexible materials. It detects cracking and damage after repeated bending and is applicable to SATRA TM55, ISO 17694, ISO 5402-1, DIN 53351 and other leather testing standards. The tester supports repeated Bally flexing tests and can be used for both dry and wet material evaluation.

The Low Temperature ROSS Flexing Tester GT-KB05B evaluates the flexing and crack resistance of rubber and footwear sole materials under low-temperature conditions. It is suitable for ASTM D1052, SATRA TM60, BS 5131:2.1, ISO 5423 and related standards. By combining ROSS flexing with controlled low-temperature testing, it helps assess footwear durability in cold environments.

The Low Temperature Bally & ROSS Resistance Flexing Tester GT-KB05C combines Bally and ROSS flexing methods for testing footwear materials under low-temperature conditions. It can be used for leather, coated fabrics, rubber and other flexible materials according to standards such as SATRA TM55, ISO 17694, ASTM D1052 and SATRA TM60. The combined design allows laboratories to perform different flexing tests in controlled cold environments.

The Low Temperature Flexing Tester GT-KC10C is designed to evaluate the flexing resistance of footwear uppers, leather, coated fabrics and other flexible materials under controlled temperatures. It supports Whole Shoes, Upper, Bally and ROSS flexing methods and can be applied to standards including SATRA TM92, SATRA TM55, ISO 5423, EN ISO 20344 and ASTM D1052. Its temperature range is approximately -40°C to 100°C.

The Comprehensive Cold Flexing Tester GT-KC15 is designed for evaluating footwear materials under low-temperature flexing conditions. It supports ROSS, Upper and Bally flexing tests for leather, coated fabrics and other footwear materials. The tester provides temperature control from approximately -40°C to 100°C, touch screen operation and automatic test control, making it suitable for multiple cold flexing test requirements.

The Low Temperature ROSS Whole Sole Flexing Tester GT-KB05E is designed to evaluate the crack resistance of complete sole materials during repeated ROSS flexing at low temperatures. It is suitable for rubber, PU, PVC, TPR and similar sole materials and can be used with ASTM D1052 and related footwear flexing methods. The combination of whole-sole testing and low-temperature control helps assess sole durability in cold conditions.

The Universal Outsole Belt Flexing Tester GT-KB55 is designed to evaluate the flexing durability of outsole belts and related flexible footwear materials. Its dedicated testing structure provides stable repeated bending and is suitable for laboratories performing footwear material durability testing according to the applicable test method.

The Universal Bally Resistance Flexing Tester GT-KB58 is designed to evaluate the resistance of leather, synthetic leather, coated fabrics and other footwear materials to repeated Bally flexing. It can be used with Bally-related methods such as SATRA TM55, ISO 17694 and ISO 5402. The tester provides stable specimen clamping and controlled repeated bending for material crack resistance evaluation.
