Understanding Shoe Size Systems

US Shoe Sizes

The United States uses a barleycorn-based system where each full size represents approximately 1/3 inch (8.47mm). Men's and women's sizes use different scales - women's sizes run about 1.5 sizes larger than men's for the same foot length. Half sizes are common and represent 1/6 inch increments.

UK Shoe Sizes

The British system also uses barleycorns (1/3 inch) but with a different starting point than US sizing. UK sizes are typically 0.5-1 size smaller than US men's sizes and about 2 sizes smaller than US women's sizes. The UK system is used in the United Kingdom, Ireland, Australia, New Zealand, India, and South Africa.

EU (European) Shoe Sizes

The European sizing system, also known as Paris Points, measures shoe length in units of 2/3 centimeter (6.67mm). EU sizes are consistent across genders - both men's and women's shoes use the same scale, though the available range differs. This system is used throughout Continental Europe.

Japan/Mondopoint (CM)

Japan uses the Mondopoint system, which is the international standard (ISO 9407). It directly measures foot length in centimeters. This is considered the most accurate system since it corresponds directly to actual foot measurements rather than arbitrary unit scales.

Mexico (MX)

Mexican shoe sizes are based on foot length in centimeters, similar to the Mondopoint system. They correspond closely to Japanese sizes, making conversion between these systems straightforward.

Brazil (BR)

Brazilian sizes follow a similar pattern to European sizes, using Paris Points. The scale is slightly different but conversion follows predictable formulas.

Korea (KR)

Korean sizes use millimeters, representing foot length in mm. A size of 270 means the shoe is designed for a foot approximately 270mm (27cm) long.

How to Measure Your Foot

1. Prepare materials: Get a blank piece of paper, a pencil, and a ruler or measuring tape
2. Position your foot: Stand on the paper with your heel against a wall or straight edge
3. Mark the longest point: Have someone mark the tip of your longest toe (usually big toe or second toe)
4. Measure the distance: Measure from the wall/edge to the mark in centimeters
5. Measure both feet: Repeat for the other foot and use the larger measurement
6. Best time to measure: Measure at the end of the day when your feet are slightly larger

Frequently Asked Questions

How do I convert US shoe size to EU?

To convert US shoe size to EU: For men, add approximately 33 to your US size (US 10 ≈ EU 43). For women, add approximately 31 to your US size (US 8 ≈ EU 39). These are approximate conversions as sizing varies between brands.

What is Mondopoint shoe sizing?

Mondopoint is an international shoe sizing standard based on foot length in millimeters or centimeters. Japan uses this system. For example, a 27 cm Mondopoint size means the shoe is designed for a foot approximately 27 cm long. This system is considered the most accurate as it directly measures foot length.

Why do shoe sizes vary between brands?

Shoe sizes vary between brands due to different lasts (foot-shaped molds), design philosophies, target markets, and historical sizing conventions. Italian brands often run smaller, while American athletic brands may run larger. Always check brand-specific size charts when buying shoes online.

How do I measure my foot for accurate shoe sizing?

To measure your foot: 1) Stand on paper with your heel against a wall, 2) Mark the longest point of your foot, 3) Measure from the wall to the mark in cm or inches, 4) Measure both feet and use the larger measurement, 5) Measure at the end of the day when feet are slightly larger.

What is the difference between UK and US shoe sizes?

UK and US shoe sizes use similar scales but with an offset. For men's shoes, US sizes are typically 0.5 to 1 size larger than UK (UK 9 ≈ US 9.5-10). For women's shoes, the difference is about 2 sizes (UK 6 ≈ US 8). Both systems use barleycorn increments (1/3 inch = one size).

Should I buy bigger shoes for wide feet?

For wide feet, look for shoes labeled "Wide" (W), "Extra Wide" (EW/XW), or specific width sizes (D for men's standard, B for women's standard, E/EE for wide). Simply buying a larger length size will make the shoe too long and can cause tripping or blisters.
