How to Measure Your Shoe Size Accurately
While these charts are helpful, measuring your foot provides the most accurate sizing information. Here’s how:
- Trace your foot: Place a piece of paper on the floor against a wall. Stand on the paper with your heel against the wall.
- Mark the longest point: Mark the longest point of your foot on the paper, which is usually the tip of your big toe.
- Measure the length: Measure the distance from the edge of the paper (where your heel was) to the mark in inches or centimeters.
- Compare to charts: Use the inch or cm measurements and the charts above to find your corresponding US, Euro, and UK sizes.
Remember, it’s best to measure both feet as one may be slightly larger than the other. Always use the measurement of the larger foot when choosing your shoe size.
FAQ & Tips for Perfect Shoe Fit
-
What if I’m between sizes? Sizing up is generally recommended, especially for athletic shoes like running shoes or hiking boots. Extra room helps accommodate foot swelling during activity and prevents discomfort.
-
Does half a size really matter? Absolutely! Even half a size difference can significantly impact comfort. Shoes that are too small can lead to blisters, lost toenails, and bunions, common issues for runners and hikers.
-
Is it normal to have different sized feet? Yes, it’s very common. Always fit shoes to your larger foot.
-
How should shoes fit – tight or loose? Shoes should be neither too tight nor too loose. You should have about a thumb’s width of space between your longest toe and the shoe’s end. You should also be able to fit an index finger snugly between your heel and the back of the shoe.
-
Best time to try on shoes? Try shoes on at the end of the day. Your feet swell throughout the day, especially after being on your feet or exercising. Trying shoes on when your feet are largest helps ensure a comfortable fit all day long.
-
Will these charts guarantee a perfect fit? These charts are a great guide, but variations exist between brands and shoe styles. For the most accurate fit, especially for specialized footwear like running shoes, consider visiting a specialty shoe store where experts can measure your feet and provide personalized fitting advice using tools like a Brannock device.
