Overview
FprCEN ISO/TS 20955 (ISO/TS 20955:2024) defines performance requirements and test methods for insoles used in all kinds of footwear. Its primary purpose is to assess the fitness for purpose of insole components - ensuring suitability for the intended end use - and to provide a common reference for manufacturers and suppliers involved in insole specification, testing and quality control.
Key topics and technical requirements
- Scope and classification: Insoles are classified by exposure/class (A–D) according to intended use:
- Class A: slight exposure (infant shoes, slippers, indoor, fashion)
- Class B: medium (casual shoes)
- Class C: high (school shoes, adult work shoes not PPE, general sports)
- Class D: heavy (heavy work, trekking, sports purpose)
- Essential vs additional requirements: All essential requirements must be met; additional requirements may be agreed between supplier and manufacturer.
- Referenced test methods: The Technical Specification refers to established ISO test methods for insoles, including methods for:
- Delamination resistance (ISO 20866)
- Heel‑pin holding strength (ISO 20867)
- Abrasion resistance (ISO 20868)
- Resistance to stitch tear (ISO 20876)
- Water absorption/desorption (ISO 22649 / ISO 2264 method B)
- Dimensional stability (ISO 22651)
- Sample preparation and conditioning (ISO 17709)
- Representative performance criteria (as given in the specification):
- Minimum delamination resistance values for fore and seat parts, wet/dry conditions (vary by class)
- Stitch‑tear resistance thresholds for sewn insoles
- Abrasion criteria (no significant changes before specified cycle counts)
- Heel pin holding strength thresholds by heel height (dry/wet)
- Dimensional stability limits (increase/shrinkage ≤ 2.0 %)
- Optional water absorption/desorption targets (e.g., absorption ≥ 70 mg/cm, desorption ≥ 60 %)
- Marking and labelling: Optional. If referenced, only insoles meeting all essential requirements may be marked; marking must include manufacturer identification, intended class and reference to the document.
Applications
- Quality control and incoming inspection of insole components
- Product development and material selection for footwear brands and suppliers
- Contractual specification between insole manufacturers and footwear OEMs
- Laboratory testing and conformity assessment for component performance
- Comparative benchmarking of insoles across applications (casual, sport, work, children’s footwear)
Who should use this standard
- Insole and footwear component manufacturers and suppliers
- Footwear brands and OEM product teams
- Test laboratories and certification bodies
- Procurement, quality assurance and R&D teams focused on footwear component 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.
