How accurate are shoe size conversions?

Our conversions are based on official international standards and are accurate within half a size. However, we recommend trying on shoes when possible as sizing can vary between brands.

Do shoe sizes differ between men and women?

Yes, there is typically a 1.5 size difference between men's and women's shoes. For example, a women's size 8 is equivalent to a men's size 6.5.

What if my size falls between two sizes?

If your measurement falls between sizes, we recommend going up to the larger size for comfort, especially for athletic shoes or boots.

Frequently Asked Questions

🦶 How to Measure Your Feet

1. Trace Your Foot

The most accurate method for home measurement:

Diagram showing how to trace a foot for shoe sizing: place foot on paper, hold pen vertical, trace outline

Place a piece of paper on the floor against a wall.
Stand on the paper with your heel against the wall.
Hold a pen vertically (90°) and trace your foot outline.

2. Measure Length & Width

Use a ruler to measure the length from the heel line to your longest toe mark.
Measure the width at the widest part of your foot trace.
Pro Tip: Subtract 0.2 inches (5mm) from length to account for the pencil width.

👟 Fit Check: The Thumb Test

Is it the right size?

There should be about a thumb's width of space between your longest toe and the end of the shoe.
The heel should fit snugly without slipping.
The widest part of your foot should align with the widest part of the shoe.

Understanding US to UK Conversion

Shoe sizing can vary significantly between brands, but the international standard conversions provide a reliable baseline. When converting from US to UK, keep in mind:

US Sizes are based on the Brannock device system.
EU Sizes (Paris point) are based on centimeters (2/3 cm per size).
UK Sizes are similar to US but generally run 1 size smaller (e.g. US 10 ≈ UK 9).
CM/JP represents the actual foot length in centimeters, often considered the most accurate method.

Top Tip: If you are buying running shoes or boots, size up by 0.5 to allow for toe movement.
