Overview
ISO/TS 20961:2024 specifies performance requirements and associated test methods for shank components used in footwear, irrespective of material. The Technical Specification is intended to help manufacturers and suppliers assess the suitability of shanks for end use and to verify fitness for purpose. It establishes essential performance thresholds and references the relevant test methods and sampling procedures.
Key Topics
- Scope and purpose: Applies to shanks for all kinds of footwear as defined in the document and can be used as a reference by manufacturers and suppliers.
- Classification: Footwear is classified by exposure into four classes to reflect intended use:
- A (slight) - infant shoes, slippers, indoor and fashion shoes
- B (medium) - casual shoes, school shoes, some adult work shoes (not PPE)
- C (high) - sport shoes, heavy work shoes (not PPE), trekking/hiking
- D (heavy) - purpose sports shoes
- Performance requirements: Two primary properties are specified with mandated test methods:
- Fatigue resistance (ISO 18895) - required minimum cycles depend on heel height (measured vertically at the back):
- < 50 mm: ≥ 3 000 cycles
- 50 mm to 74 mm: ≥ 8 000 cycles
- 75 mm to 99 mm: ≥ 20 000 cycles
- ≥ 100 mm: ≥ 60 000 cycles
- Longitudinal stiffness (ISO 18896) - minimum stiffness values vary by heel height (unit as in the Technical Specification):
- < 50 mm: ≥ 400 kN · mm²
- 50 mm to 74 mm: ≥ 800 kN · mm²
- 75 mm to 99 mm: ≥ 1 200 kN · mm²
- ≥ 100 mm: ≥ 1 600 kN · mm²
- Fatigue resistance (ISO 18895) - required minimum cycles depend on heel height (measured vertically at the back):
- Sampling and preparation: When samples are taken from finished footwear they shall be prepared according to ISO 17709; results are rounded per ISO 80000-1.
- Marking and labelling: Optional. If referenced, only shanks that comply with all requirements may be marked. Required marking details include manufacturer identification, heel height (mm) and a reference to ISO/TS 20961:2024. Such references should not be placed on parts of the insole visible after finishing.
Applications
- Quality control and incoming inspection for shank components
- Product development and material selection to meet durability and stiffness targets
- Supplier specifications and procurement requirements
- Demonstrating fitness for purpose in footwear categories from infant fashion shoes to heavy outdoor and sport footwear

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
in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for the different types
of ISO document should be noted. This document was drafted in accordance with the editorial rules of the
ISO/IEC Directives, Part 2 (see www.iso.org/directives).
ISO draws attention to the possibility that the implementation of this document may involve the use of (a)
