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 documents 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)
patent(s). ISO takes no position concerning the evidence, validity or applicability of any claimed patent
rights in respect thereof. As of the date of publication of this document, ISO had not received notice of (a)
patent(s) which may be required to implement this document. However, implementers are cautioned that
this may not represent the latest information, which may be obtained from the patent database available at
www.iso.org/patents. ISO shall not be held responsible for identifying any or all such patent rights.

Introduction
Lasts are the base for footwear production. Standardization related to lasts can guide and regulate the
design and production of lasts, thereby improving the fitting and comfort of footwear products.
This document includes partial information obtained from a survey carried out based on the Chinese
population in relation to GB/T 3293, the Chinese standard on lasts, which has undergone two revisions and
has been implemented for over 40 years.
This technical report not only allows footwear traders, manufacturers, and other stakeholders from various
countries to understand the last system, but also strengthens communication and cooperation in the design
and standardization of lasts.

reference last
last with dimensions as reference size
3.2

4 Classification
Footwear size can be classified according to Table 1. For each classification, reference sizes are given.

5 Last dimensions
5.1 Last dimensions measurement
Measurement of last dimensions can be carried out according to ISO 19409.
5.2 Interval of last dimensions
5.2.1 Length grading interval
In practice, 10 mm intervals are commonly referred to as whole sizes, and 5 mm intervals as half sizes.
5.2.2 Ball girth grading interval
In practice, 7 mm intervals are commonly referred to as whole sizes, and 3,5 mm intervals as half sizes.
5.2.3 Width grading interval
In practice, 7 mm intervals are commonly referred to as whole sizes, and 3,5 mm intervals as half sizes.
5.2.4 Heel height grading interval
In practice, 5 mm intervals are commonly referred to as height grading, starting at 20 mm for men last and
at 25 mm for women last.
5.3 Regular and variable reference dimensions
5.3.1 The lengths of key points on the last bottom and ball girth are regular reference dimensions.
5.3.2 The widths of key points on the last bottom (including inner width of big toe, outer width of little
toe, inner width of first metatarsal, outer width of fifth metatarsal, tread width of heel, etc.) are regular
reference dimensions, but half size up or down is allowed based on the width reference dimensions, that is,
the width of each part on the last bottom can be set at any value within the range of plus or minus half size.
5.3.3 The other dimensions of the last are variable.

5.4 Back of last
Regardless of style of toe design, the dimension of back of last behind the ball girth can remain unchanged
for a last with the same type and same heel height.
5.5 Design allowance
5.5.1 Based on regular reference dimensions of the various length, girth and width on a last with the same
footwear size and type, the design allowance can be added to the toe allowance.
5.5.2 The design can be based on regular and variable reference dimensions and other dimensions to
achieve comfort and aesthetics of the footwear.
5.5.3 Design allowance can be variable as long as it does not affect wearing, but this does not apply to
safety footwear and children’s footwear.
6 Last systems
6.1 General
This clause contains the last systems for men, women and children footwear, and for different footwear types.
6.2 Last system for men footwear
The dimensions of reference last for men footwear are given in Table 2 and Table 3.
