Men's Shoe Size Guide: US, EU, UK, CM and Inches
By Viet Anh Nguyen on Sep 26, 2026
Choosing the right size is one of the most important parts of ordering handmade leather shoes online. Colin Martin displays US, EU and UK equivalents together with foot length in centimetres and inches, so customers in the United States, Europe and Vietnam can compare easily.
Start with your usual US men’s size
If you normally wear a consistent US men’s size in quality dress shoes, that is the best starting point. Shoe sizing can vary slightly between brands and lasts, so consider the shape of the shoe as well as the number.
How to use the size chart
Use the US column first, then check the matching EU and UK values. The chart also shows approximate foot length in centimetres and inches. These measurements are a reference to help you compare systems, not a mandatory step before ordering.

Do I need to measure my foot?
No. Foot measurement is optional. Most customers can choose their usual size and contact us if they are between sizes or unsure about the fit. If you do measure, stand naturally and measure both feet at the end of the day. Use the longer foot as your reference.
Consider the shoe style
Oxford shoes can feel more structured and close-fitting. Derby shoes usually offer a little more room through the instep. Loafers should feel secure without slipping at the heel, while boots may be worn with thicker socks. The last and construction also influence the way a shoe feels.
Need help before ordering?
Tell us the size you normally wear, the style you are considering and how you plan to use the shoes. Our team can help you choose between Oxford, Derby, Loafer, Monkstrap and Boot styles. Colin Martin makes each pair to order in Hanoi and ships worldwide.
