Sneaker sizes can be confusing, especially since several models share the same CM measurements but fit very differently on the foot. Here’s a quick guide to measuring your foot and finding the right shoe size, regardless of the brand.
How to measure your foot
- Stand with your heel against a wall.
- Mark the floor at the tip of your longest toe.
- Measure the distance from the wall to the mark in cm.
- Choose a size where the insole is 0.5–1 cm longer than your foot.
- If you are between two sizes, we often recommend choosing the larger one—but always follow the specific brand/model guide, as sizing varies from model to model.
EU, US and UK shoe sizes
Size scales vary from country to country, so an EU 42 does not correspond to the same number in US or UK sizing. The table below covers the most common adult sizes and can be used to convert between EU, US and UK.
Note: This table is only a general conversion chart. The fit varies between brands and models—Nike, Adidas, Yeezy Slides and UGG, for example, fit very differently even in the same EU size. Always check the specific brand’s/model’s own size guide, or the size recommendation shown directly on the product page, before choosing a size.

FAQ
How do I find the right shoe size?
Measure your foot in cm and choose a size where the insole is 0.5–1 cm longer than your foot. Then use the specific brand’s size guide, as the fit varies between models.
How do I measure my foot at home?
Stand with your heel against a wall, mark the floor at the tip of your longest toe, and measure the distance in cm. Do this while standing, as your foot takes up more space under weight.
Do sneakers run large or small?
It varies greatly from brand to brand, and even more from model to model:
-
Adidas: often runs slightly small—most people go up half a size.
-
Nike/Jordan: often runs slightly small—going up half a size is common, but Air Force 1 is an exception and typically fits true to size or slightly large.
-
Yeezy Slides: run significantly large—expect to go up one to two full sizes.
-
UGG: runs small—consider choosing one size up.
-
New Balance: usually fits true to size, but some models (e.g. certain 550/990 variants) are slightly roomy.
Always check the specific brand’s or model’s own size guide, as there are exceptions within every brand.
What should I do if I am between two sizes?
If you are between two sizes, we often recommend choosing the larger one—but always follow the specific brand/model guide, as some models (e.g. Yeezy Slides) require a larger size increase, while others (e.g. New Balance) fit well in your usual size. For many products, we also show a specific size recommendation directly next to the size selection, so you can see the exact recommendation for that model without having to work it out yourself.
Is there a difference between EU, US and UK shoe sizes?
Yes, the three systems use different scales, so the same foot length corresponds to different numbers in EU, US and UK sizing. Always use the CM measurement as the most precise point of comparison.
