Frequently asked questions

Is the Shoe Size Converter really free?
Yes. Free with no signup and no limits.
Which size systems are supported?
US, UK, and EU sizes for men, women, and kids, using standard US retail conversions.
How do I measure my foot correctly?
Measure from heel to longest toe while standing, late in the day when feet are at their largest, and enter the length in inches. The tool adds about 0.3 inches of wiggle room for comfort.
What is Mondo or CM sizing?
Mondo sizing is simply your foot length in centimeters. Because it is a direct measurement rather than a regional scale, it is the most reliable system for ordering shoes online.
What if I am between sizes?
Size up for comfort. The converter notes this too, since fit varies by brand and a slightly roomier shoe beats a cramped one.
Why do the same sizes fit differently across brands?
Brands use slightly different lasts and fit philosophies even on the same scale. The converter uses standard retail conversions, so when precision matters, check the brand’s own chart or go by your CM measurement.
