Overview
ISO/TS 20995:2024 specifies performance requirements and test methods for stiffeners and toe puffs used in footwear. The Technical Specification is intended as a reference for manufacturers and suppliers to assess component suitability for end use and fitness for purpose. It applies to stiffeners and toe puffs for all kinds of footwear as classified in the document and defines when and how samples shall be prepared and tested.
Key Topics
- Classification: Components are classified by exposure and shoe type (Classes A–D), ranging from slight (infant and fashion shoes) to heavy (trekking, work and similar sports shoes).
- Test methods: The document references established test procedures including ISO 20863 (bondability), ISO 20864 (mechanical characteristics and resilience), and ISO 48-4 (Shore hardness). Sample preparation and conditioning follow ISO 17709.
- Performance requirements: Table 2 in the specification lists class-specific requirements addressing:
- Bondability: Minimum bond strength thresholds in dry and wet conditions, with different criteria when a lining is present or absent.
- Mechanical characteristics: Shape retention after repeated deformations and collapsing-load resilience requirements to ensure durability and function.
- Hardness: Class-based hardness ranges as determined by ISO 48-4 (Shore):
- Class A: ≤ 30 N
- Class B: 30 N to 80 N
- Class C: 80 N to 130 N
- Class D: ≥ 130 N
- Resilience (ISO 20864): Minimum resilience percentages increase by class (e.g., Class A higher than Class D).
- Moisture resistance: Minimum moisture-resistance requirements are specified per class to reflect intended use and exposure.
Applications
This Technical Specification is practical for:
- Footwear component manufacturers validating bondability, shape retention, resilience, hardness, and moisture resistance of stiffeners and toe puffs.
- Suppliers providing traceable data to footwear brands and converters to demonstrate component fitness for specific shoe classes.
- Product development and quality control teams integrating standardized test methods into acceptance criteria and supplier specifications.
By following ISO/TS 20995:2024, organizations can align component evaluation with international test methods and class-based performance expectations, reducing risk of premature failure and ensuring consistent product performance.

Foreword
ISO (the International Organization for Standardization) is a worldwide federation of national standards
bodies (ISO member bodies). The work of preparing International Standards is normally carried out through
ISO technical committees. Each member body interested in a subject for which a technical committee
has been established has the right to be represented on that committee. International organizations,
governmental and non-governmental, in liaison with ISO, also take part in the work. ISO collaborates closely
with the International Electrotechnical Commission (IEC) on all matters of electrotechnical standardization.
The procedures used to develop this document and those intended for its further maintenance are described
