Nike has today introduced their latest design tool, "Nike Fit," which aims to help customers find the perfect shoe size no matter which Nike sneaker they're looking to purchase. 

Using your smartphone’s camera, Nike Fit will scan your feet, collecting 13 data points mapping your foot within a matter of seconds. Nike Fit will then provide a perfect fit for each Nike shoe style.

According to Nike, the Nike Fit scanning solution uses a combination of computer vision, data science, machine learning, artificial intelligence and recommendation algorithms. It does this by measuring the full shape of both feet, offering the ability to know your truly perfect fit for each Nike shoe style.

How Nike Fit Works

While shopping within the Nike app, when you go to select your size, there will be a new option that asks whether you’d like to try Nike Fit. Using your phone's camera to scan your feet, Nike Fit will churn out the size you need.

How to Apply It

Once you’ve scanned your feet, you will be offered a “best fit for you” recommendation for that footwear wherever you shop —  in the app or in store. For example, if you have used Nike Fit to scan your feet and you go to purchase a Nike Cortez on the Nike app, you won’t see a run of sizes anymore.

Instead, you’ll just see your size for that particular shoe. Then, if you go to buy a Nike Air Zoom Pegasus you might see another size. That’s because different shoes are made with different performance intent – a running shoe works best for the athlete when a little more snug while a sportswear shoe is designed to have more room for everyday wear.
