Overview
SIST-TS CEN ISO/TS 20955:2026 - Footwear – Performance requirements for components for footwear – Insoles (ISO/TS 20955:2024) is an international technical specification developed by CEN and ISO. This document defines the essential and additional performance requirements for insole components used in all types of footwear. It specifies appropriate test methods to assess compliance with these requirements, ensuring insoles are suitable for their intended end use and meet standards of durability, safety, and comfort. The standard serves as a reference for manufacturers and suppliers when designing, producing, and sourcing insole components.
Key Topics
Scope and Applicability
- Covers insoles for all footwear categories, from infant shoes to heavy-duty trekking and sports footwear.
- Applies to both leather and non-leather insoles, with specific requirements based on material and footwear type.
- Usable by both manufacturers and suppliers as a quality and compliance reference.
Classification of Footwear
- Divided into four classes based on use and exposure:
- Class A: Slight exposure (e.g., infant shoes, slippers)
- Class B: Medium exposure (e.g., children's and adult casual/work shoes)
- Class C: High exposure (e.g., school shoes, general sport shoes)
- Class D: Heavy exposure (e.g., trekking, hiking footwear)
- Divided into four classes based on use and exposure:
Performance Requirements
- Essential and additional requirements for insoles, including:
- Delamination resistance - Ensures bonding strength in both dry and wet conditions.
- Resistance to stitch tear - Critical for sewn insoles' structural integrity.
- Abrasion resistance - Prevents significant wear during use.
- Heel pin holding strength - Verifies the insole's ability to retain heels securely.
- Dimensional stability - Limits size change due to moisture or wear.
- Water absorption and desorption - Measures the insole's ability to manage moisture, contributing to comfort and hygiene.
- Essential and additional requirements for insoles, including:
Marking and Labelling
- Marking is optional but, if performed, must indicate manufacturer, class of footwear, and reference to the standard, in a non-visible part of the finished product.
Applications
SIST-TS CEN ISO/TS 20955:2026 is practical in a variety of scenarios across the footwear industry:
- Product Development: Assisting designers and engineers in selecting or specifying insole materials that meet expected performance.
- Quality Assurance: Manufacturers use the test methods and requirements to implement robust quality control and ensure consistent product reliability.
- Supplier Evaluation: Footwear brands and OEMs evaluate supplier compliance, helping reduce failures or returns due to poor insole performance.
- Regulatory Compliance: Ensures that insoles meet international best practices for comfort, durability, and user safety.
- Market Claim Support: Brands referencing this standard can credibly claim technical compliance, supporting product differentiation and consumer trust.
Related Standards
For comprehensive evaluation of footwear insoles, SIST-TS CEN ISO/TS 20955:2026 references several related international standards:
- ISO 17709 – Sampling location, preparation and conditioning of samples and test pieces
- ISO 19952 – Footwear vocabulary
- ISO 20866 – Test methods for insoles: Delamination resistance
- ISO 20867 – Test methods for insoles: Heel pin holding strength
- ISO 20868 – Test methods for insoles: Abrasion resistance
- ISO 20876 – Test methods for insoles: Resistance to stitch tear
- ISO 22649 – Test methods for insoles and insocks: Water absorption and desorption
- ISO 22651 – Test methods for insoles: Dimensional stability
Conclusion
By following SIST-TS CEN ISO/TS 20955:2026, the footwear industry can achieve reliable and standardized assessment of insole performance. This not only facilitates fair competition and innovation but also ensures consumers receive footwear that meets established criteria for comfort, durability, and safety. For businesses focused on quality and global market access, adherence to this standard is a valuable competitive advantage.
