Finding the perfect fit in every pair of running shoes can be tricky, and Nike wants to solve that woe. Just because you’re a 10.5 in the Nike Free doesn’t mean you should buy a 10.5 for the Air Max golf shoes, which is why Nike launched Nike Fit. It’s a scanning technology that analyzes 13 data points from a photo of your feet and pops out the perfect size for you given your foot dimension. Buying the wrong size of shoes and having to return them is time-consuming and annoying. While we haven’t been able to test the technology, it’s starting to roll out this summer in stores and via the app. Here are a few of our current Nike sneaker obsessions to help you get started.
