Frequently asked questions
How do I accurately measure foot length in cm?
Stand bare-foot on paper with heel against a wall, mark the tip of your longest toe, and measure the distance.
What is the difference between US Men's and Women's shoe sizes?
US Women's sizing is typically 1.5 sizes larger than US Men's for the same foot length (e.g., Men's 8.5 = Women's 10).
What should I do if my measurement is between sizes?
Always round up to the next half size for comfort, as feet expand during walking and throughout the day.
What is Mondopoint sizing?
Mondopoint is the international ISO standard based directly on foot length in millimeters (e.g., 270 = 27 cm).
Why do shoe sizes vary by brand?
Brands use different shoe lasts and fitting allowances, causing slight sizing variances between manufacturers.
How do you convert UK shoe size to EU?
Add approximately 33 to 33.5 to the UK size to find the equivalent EU size (e.g., UK 8 + 33.5 = EU 41.5/42).
