A shoe size is a numerical indication of the fitting size of a shoe for a person. A shoe is an item of Footwear. Shoes may vary from a simple Flip-flop to a complex Boot. Several different shoe-size systems are still used today worldwide. Some regions use different shoe-size systems for different types of shoes (e. g. , men's, women's, children's, sport or safety shoes).

Foot length versus shoe length

The length of a foot is commonly defined as the distance between two parallel lines that are perpendicular to the foot and in contact with the most prominent toe and the most prominent part of the heel. The foot is an Anatomical structure found in many Animals It is the terminal portion of a limb which bears weight and allows Locomotion. In Geometry, two lines or planes (or a line and a plane are considered perpendicular (or orthogonal) to each other if they form congruent Foot length is measured with the subject standing barefoot and the weight of the body equally distributed on both feet.

The size of the left and right foot is often slightly different - in this case both feet are measured and the shoe size based on the larger foot.

Each shoe is suitable for a small interval of foot lengths. The length of the inner cavity of a shoe must typically be 15–20 mm longer than the length of the foot, but this relation varies between different types of shoes.

There are three characteristic lengths that a shoe-size system can refer to:

All these measures differ substantially from each other for the same shoe.

Length unit

The following length units are commonly used today to define shoe-size systems:

Customary units

Metric units

International standards

The International Standard is ISO 9407:1991, Shoe sizes — Mondopoint system of sizing and marking,[1] that recommend a shoe-size system known as Mondopoint. It is based on the mean foot length for which the shoe is suitable, measured in millimetres. A Mondopoint shoe label can optionally also specify the width of the foot, again in millimetres.

European standard EN 13402,[2], used also for clothes, recommends instead that shoes should be labeled with the interval of foot lengths for which they are suitable, measured in centimetres. EN 13402 is a European standard for labelling clothes sizes It is based on body dimensions measured in Centimetres It aims to replace many older national dress-size

Traditional shoe sizes by country

N. B. Most of the shoe-size systems listed in this section are not formally standardized. The exact relationship between a labelled shoe size and the interval of foot lengths for which that shoe is suitable can vary substantially between different manufacturers. The following descriptions may only approximate the exact sizing systems used by individual manufacturers. One source of discrepancy occurs when a shoe manufactured according to one shoe-size system is labelled in another system.

English system

Britain

Shoe size in Britain is based on the length of the last, measured in barleycorns (thirds of an inch) starting from the smallest practical size, which is size zero. The United Kingdom of Great Britain and Northern Ireland, commonly known as the United Kingdom, the UK or Britain,is a Sovereign state located English unit is the American name for a unit in one of a number of systems of Units of measurement, some obsolete and some still in use in present-day USA, the Inches redirects here To see the Les Savy Fav album see Inches.

A child's size zero starts with the width of a hand (four inches - twelve barleycorns) and goes up to two hand-widths, which is a size 12 (eight inches). See also Hand A hand (or handbreadth) is a unit of length Measurement, originally based on the breadth of a Male Human hand Thus, the calculation for a child shoe size in the UK is:

child shoe size = 3 * last length in inches − 12

An adult size zero then starts at the next size up (eight and one-third inches) and each size up continues the progression in barleycorns. [3]. The calculation for an adult shoe size in the UK is thus:

adult shoe size = 3 * last length in inches − 25

United States and Canada

Shoe sizes in North America are similar to those in Britain but start counting at one rather than zero and so equivalent sizes are one greater. (This is similar to the way that floors in buildings are numbered from one rather from zero in these regions).

So, the calculation for a male shoe size in the USA or Canada is:

male shoe size = 3 * last length in inches − 24

Women's sizes are almost always determined with the "common" scale, in which women's sizes are equal to men's sizes plus 1. 5 (for example, a men's 10. 5 is a women's 12). In other words:

female shoe size (common) = 3 * last length in inches − 22. 5

In the less popular scale, known as the "standard" or "FIA" (Footwear Industries of America) scale, women's sizes are men's sizes plus 1 (so a men's 10. 5 is a women's 11. 5).

female shoe size (FIA) = 3 * last length in inches − 23

Children's sizes are equal to men's sizes plus 12. 33. Thus girls' and boys' sizes do not differ, even though men's and women's do.

child shoe size = 3 * last length in inches − 11. 67

For the international market, ISO 9407 is used. Globalization (or globalisation) in its literal sense is the process of transformation of local or regional phenomena into global ones

Australia

male shoe size = 3 * last length − 22. 5cm

female shoe size (Australia/NZ) = 3 * last length − 20. 5cm

Czech Republic

Although the French system prevails, the English one is widely spread. [1], [2]

French system

This system is the most common system worldwide, and the most used in number of people.

Europe

In France, Germany,[4] Italy, Spain[5] and most other continental European countries, the traditional shoe size is the length of the last expressed in Paris points (a Paris point is 2/3 of a centimetre). This article is about the country For a topic outline on this subject see List of basic France topics. Germany, officially the Federal Republic of Germany ( ˈbʊndəsʁepuˌbliːk ˈdɔʏtʃlant is a Country in Central Europe. Italy (Italia officially the Italian Republic, (Repubblica Italiana is located on the Italian Peninsula in Southern Europe, and on the two largest Spain () or the Kingdom of Spain (Reino de España is a country located mostly in southwestern Europe on the Iberian Peninsula. A last is the Form used in Shoemaking to shape a Shoe in the rough form of a human Foot. In other words, it is 1. 5 l, where l is the length of the last in centimetres. A centimetre ( American spelling: centimeter, symbol cm) is a unit of Length in the Metric system, equal to one hundredth Thus for example, for shoe types where the last is 2 cm longer than the foot for which the shoe will fit, the size is 1. 5 f + 3, where f is the foot length in centimetres.

China

Shoe sizes in China are basically the same as in the French system. China ( Wade-Giles ( Mandarin) Chung¹kuo² is a cultural region, an ancient Civilization, and depending on perspective a National

Other

Japan

Shoe sizes in Japan are represented by the length of the shoe in centimetres. For a topic outline on this subject see List of basic Japan topics. [6] Size designations are independent of wearer's gender. However, for women sizes typically range from 23 cm to 25 cm (in increments of 0. 5 cm); for men the sizes typically range from 24 cm to 28 cm (increments of 0. 5 cm). Japanese feet (hence shoes) appear to be on average shorter and wider than those of American or Europeans. Children's shoes are also measured in centimetres.

Korea

Shoe sizes in Korea have no respect to gender, but simply correlate to the length of the foot in millimeters. Korea is a geographic area composed of two sovereign countries a civilization and a former state situated on the Korean Peninsula in East Asia. Sizes are available in multiples of 5. [7]

Brazil

shoe size = length of foot (cm) / 0. 65

Width or girth designators

Some manufacturers offer shoes of different width for the same foot length. Such shoes are then also labelled according to the width or girth of the widest part of the foot (typically measured directly behind the toes with the subject standing on both feet and wearing socks or hose).

In the Mondopoint system, the shoe size label can state in addition to the length also the width of the mean foot for which the shoe is suitable, both measured in millimetres.

A number of other ad-hoc notations for width or girth are also used. Examples include (each starting with the narrowest width):

None of these designations is formally standardized. The exact foot width for which these sizes are suitable can vary significantly between manufacturers. The A-E width indicators used by some US and UK shoe manufacturers are typically based on the width of the foot, and common step sizes are 1/4 inch (6 mm) or 3/16 inch (5 mm). The foot is an Anatomical structure found in many Animals It is the terminal portion of a limb which bears weight and allows Locomotion.
