Good questions

The short answers.

What is SizeWise?

SizeWise is a tool that helps you find the perfect shoe size for the person you scan using your mobile device. All you need is a smartphone and a blank A4 or US Letter sheet of paper on a hard surface.

Is SizeWise free to use?

Yes! It is free to use. You can scan and receive a recommended shoe size at no cost.

Do I need to scan both feet?

Yes. It's common for one foot to be slightly longer than the other. To ensure the best fit, always measure both feet.

How close should I stand relative to the foot?

Stand about a meter away, not too close, and scan at about a 45% angle. It is important to try to keep the 4 corners of the page in the frame. Align the page on the floor with the virtual page you see on screen and follow the instructions. Do this on the front and on the side for a quick easy scan.

Can I scan myself?

It is possible to scan yourself, however it can be easier if someone helps you as it can be difficult to see the phone screen. 

How accurate is the measurement?

SizeWise is highly accurate taking many measurement of length and width to the millimeter. Please note, the way the individual being measured is standing can affect the results. For the best measurement, have the person stand up straight with feet side by side, placing one foot on the A4 sheet.
