Buying shoes and clothes online can be hard, getting the exact size you need is not easy as sizes often differ by brands, the new Nike app is designed to get you the perfect shoes size as it measures your feet.
The new Nike app can measure your feet to withing a millimeter and it is capable of telling you if one of your feet is larger than the other.
To measure you feet with the app you just stand next to a wall and then point your phone at your feet, it then uses your phones camera to measure your feet. The app will then let you know the exact size shoe you need.
An if different models have different sizing, the app will let you know exactly what size you need in each different model. This seems like a great idea and a great way to make it easier to order shoes and trainers online.
