What we do

No matter if you’re the biggest sports fanatic, have a ‘minor’ shoe addiction or you own just one pair of sneakers, you know that finding the “perfect” shoe can be challenging.

We have created a way to make a 3D scan of your feet and match that profile with our own (and the world’s largest) database of 3D-scanned shoes. Our goal is to inspire people to do what they love in maximum comfort, whether it’s running a marathon, dancing all night or simply going for a stroll in the park. As an employer, we strive to translate this philosophy into a happy and balanced lifestyle for all our team members, giving them the opportunity to grow and thrive while doing what they love.
