As seen in

A shoe that really fits.

Grows a whole size with them

Children don't notice when a shoe gets too small. And a fixed size only ever fits for a short while.

With Sizeless, you simply adjust the shoe bit by bit as the foot grows. Left and right separately.

    Off on an adventure, in shoes that keep up.

Good to know: You can adjust each shoe separately, because children's feet grow differently.

What parents say

  • What I find especially practical is that you can adjust the size to fit, so the shoe grows with them for longer. That way you don't have to keep buying new shoes as soon as the children have grown a few centimetres.

  • The afternoon we picked up the parcel from the parcel locker, my two girls didn't want to take them off again “until we have to go to bed”. They love the shoes. 💜💚

Quick questions

  • How much can the shoe be adjusted?

    By a little more than one whole shoe size. So you have two sizes in one shoe.

  • Which size do I need?

    Measure the foot length while standing, heel against the wall, each foot separately. You don't need to add room for the toes. Our size finder shows you the right size.

  • Can I return the shoes?

    Yes, within 30 days. Try without risk.
