How to Measure Your Feet Accurately.
Take foot measurements in the late afternoon, as feet naturally expand during daytime activity.
Tape Paper to Floor
Tape a piece of blank paper firmly against a flat, straight wall on a hard surface (avoid thick carpet).
Trace Your Longest Toe
Stand upright with your heel touching the wall. Mark the tip of your longest toe (often the big or second toe) with a pencil held vertically.
Measure in Millimeters
Use a rigid ruler to measure the distance in millimeters from the edge of the paper to your mark. That is your Mondopoint length.

Frequently Asked Questions About Shoe Sizing.
Everything you need to know before ordering footwear across borders.
How do I find my exact international shoe size?↓
The most reliable method is measuring your bare foot length in centimeters or millimeters (Mondopoint) from the heel to the tip of your longest toe in the afternoon, then matching it against our ISO 9407 conversion tables.
Why do shoe sizes differ across brands like Nike, Adidas, and New Balance?↓
While international standards exist, individual athletic and dress shoe manufacturers utilize proprietary foot molds (lasts). For example, Nike generally runs narrower (often a half size smaller for wide feet), while Adidas and New Balance offer truer-to-scale width toe-boxes.
What does shoe width letter coding mean (B, D, 2E, 4E)?↓
In the US, 'B' is standard women's width (narrow for men), 'D' is standard men's width (wide for women), '2E' is wide men's, and '4E' is extra wide men's. Measuring around the widest ball of your foot determines the proper width letter.
How much space should be left in the toe of a shoe?↓
A proper fit requires approximately 10mm to 15mm (about a thumbnail's width) between your longest toe and the end of the shoe to accommodate natural foot splay during walking or running.
