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.
International Standards are drafted in accordance with the rules given in the ISO/IEC Directives, Part 2.
The main task of technical committees is to prepare International Standards. Draft International Standards
adopted by the technical committees are circulated to the member bodies for voting. Publication as an
International Standard requires approval by at least 75 % of the member bodies casting a vote.
In exceptional circumstances, when a technical committee has collected data of a different kind from that
which is normally published as an International Standard (“state of the art”, for example), it may decide by a
simple majority vote of its participating members to publish a Technical Report. A Technical Report is entirely
informative in nature and does not have to be reviewed until the data it provides are considered to be no
longer valid or useful.
Attention is drawn to the possibility that some of the elements of this document may be the subject of patent
rights. ISO shall not be held responsible for identifying any or all such patent rights.
ISO/TR 20881 was prepared by the European Committee for Standardization (CEN) Technical Committee
CEN/TC 309, Footwear, in collaboration with Technical Committee ISO/TC 216, Footwear, in accordance with
the Agreement on technical cooperation between ISO and CEN (Vienna Agreement).

TECHNICAL REPORT ISO/TR 20881:2007(E)

Footwear — Performance requirements for components for
footwear — Insoles
1 Scope
This Technical Report establishes the performance requirements for insoles components for footwear (not for
the finished footwear), irrespective of the material, in order to assess the suitability for the end use and/or
fitness for purpose. It also establishes the test methods to be used to evaluate the compliance with the
requirements.
This Technical Report applies to insoles for all kinds of footwear as defined in Clause 3.
This Technical Report is intended to be used as a reference between the manufacturer and the supplier. It is
not intended for third party certification.
