🔬 How does the measurement technology work?
The technology can be broken down into several steps:
- Photographing is the only one in which the user is involved. Within this process, 3 photos of your feet are automatically taken and data on the scale and angle at which each photo was taken is collected. We control the accuracy of the process using neural networks and data from the phone's accelerometer. Already at this stage, in augmented reality, you can see preliminary data on the length, width and fullness, but they are not very accurate.
- Creating a 3D model. The data is sent to the server, where a 3D model is built from the photos using our neural networks. The process takes no more than 7 seconds.
- Calculating indicators. The generated 3D model is aligned along the length, key points on the foot are found and calculations are made for the length, width, girth of the bundles, girth of the instep and girth through The heel—the same measurements taken by shoemakers all over the world for custom-made shoes. But for us, it takes no more than a second. After that, a 3D model with the calculated measurements is downloaded to the user's device.
See the video of the process below.
📄 Why do I need an A4 sheet of paper?
An A4 sheet is used to determine the scale and angle at which the photographs are taken. It is a sort of universal (which almost every home has) connecting link with fixed dimensions.
- The position of the foot on the sheet ties all 3 photographs together, so it is extremely important not to shift the foot on the sheet from photograph to photograph - they should be taken as if at the same time.
- The sheet is not used as a background. If your foot does not fit on the sheet, do not try to place it at an angle. Place it straight, without fear of going beyond the edges of the sheet.
- The sheet can have any text or pictures on it, the main thing is that it is A4 format (210 x 297), not torn, not deformed, without bent corners.
🎯 What is the measurement accuracy?
The measurement error for length and width is up to 1 mm, and the measurement error for circumference is up to 3 mm. For accurate measurements, it is important to follow the instructions provided before photographing.
The measurement error for the preliminary measurements you see during the augmented reality photo shoot is ~2 mm, and the width is calculated based only on the width of the foot. Preliminary measurements in AR do not affect the final calculations based on the 3D model.

🧦 Are there any restrictions on sock color, gender, etc.?
We've tried to remove all restrictions—it's possible with a white sock on a white sheet with a white floor. Just don't repeat the typical mistakes mentioned in the solution.
There are rare cases where neural networks make mistakes, for example, white socks with a black edge on the side that blends in/can be perceived as part of the shadow of the foot, but we're working to address that.
📏 How do I find out my size and fullness based on my measurements?
To find out your measurements (Russian, European, UK, US, etc.), you must register before or immediately after taking measurements. It's completely free and takes less than a minute.
Some sizes and fullness values depend on gender and age (adult or child) - you must specify these in your profile during registration so that we can calculate for you and provide recommendations.
👟 How do I use the measurement results?
The key parameters for choosing comfortable shoes with fasteners (laces, Velcro, buckles, etc.) are length and circumference in bunches. Such parameters as instep circumference and oblique circumference are important for shoes without fasteners, for example, loafers.
Length determines the size, and the circumference in bunches determines the fullness.
Each manufacturer sews shoes according to its own lasts and each has its own size charts. So, for example, for a foot length of 260 mm, New Balance recommends choosing the European size of its women's models 40.5, men's / unisex - 41.5, and adidas - 42⅔. By clicking the "Manufacturer sizes" button, you can see your sizes from each manufacturer (if you have not measured your feet using our solution, but know the length, you can enter (manually).
It is important to understand that the size determines only the appropriate foot length, and the width is usually average. At the same time, models made specifically for women are narrower than men's and unisex models. Therefore, if you have a non-standard width, you must take this into account when choosing shoes. After measuring your foot, we provide recommendations for your width.
If you have a non-standard width, we recommend paying attention to New Balance shoes, whose models are made for different widths. Each pair is marked not only with a numeric size, but also with a letter that determines the width in American standards (for more details, read our article on Zen). Some shoe models may have only one width option, and some have different variations. In our product cards, next to the name, it is indicated which This model may have variations in width. Additionally, some models from other manufacturers are also made for non-standard widths—select the appropriate filter in the search to find them.
You can also use the calculation results for custom-made shoesfrom shoemakers in Russia or abroad.
🦶 Is it enough to measure one foot or both?
Most people's feet are not symmetrical. Often the difference is within a couple of millimeters, but according to research, from 19% to 24% of people have a difference in the sizes of their left and right feet of at least 4 millimeters (more than half of a European foot size 1).
To determine the final size and fullness, use the largest of the lengths and the largest of the circumferences (in this case, one foot may be longer and the other fuller).
