At OnSize, every sneaker goes through a multi-step verification process, so we can guarantee the authenticity of our products 100%. We include a plastic card with every shoe that has passed the verification process, confirming its authenticity. You can only purchase shoes with such a plastic card, i.e. verified shoes, in our store or webshop.

The OnSize plastic card that comes with our sneakers is unique, so it can only be found with the shoes we sell. On one side, you can see the OnSize logo and the words “100% Verified Authentic”, while on the other side there is a QR code that leads to this page.

Another important advantage of the plastic card, in addition to the proof of authenticity, is the possibility of exchange and withdrawal. We can only return or exchange shoes that have the corresponding plastic card in an undamaged condition.
