FAQ

The easiest way is with our size finder: measure the foot yourself or print our measuring template. Measure the foot rather than going by the old shoe size. If your child is between two sizes, take the larger one and set it smaller. That way the shoe grows with them.

Find the right size

Sizeless comes in sizes EU 24 to 33, in 9 shoes from 24-25 to 32-33. Each shoe covers 2 sizes.

On the side of the shoe you can see how far it is adjusted: turquoise is Small, yellow is Medium, red is Large. Our size finder tells you which setting fits, for example: size 24-25, setting Small. Once the shoe is on Large, your child keeps wearing it until the next-but-one size fits.

Children don't notice for themselves when a shoe is getting too small. So measure their feet about once a month, ideally standing up with the heel against the wall. If the foot has grown, simply move the shoe on by one colour. Left and right separately.

Yes. Each shoe is adjusted separately. That's handy, because children's feet grow differently.

There are two tabs on the outside. With them you pull the flexible sole up at the toe box or release it. This makes the shoe bigger or smaller, inside and out. Then you fix the tabs in place and pull the strap over the hook-and-loop fastener. It takes about 30 seconds.

One full size. So you get two sizes in one shoe.

The length is what adjusts, because that's where children's feet grow the most. The wide toe box and the flexible upper also give enough room in width. With the hook-and-loop strap on top, you can fit the shoe to a high or low instep.

Sizeless was developed with physiotherapists and experts from the German Sport University Cologne. The flexible sole and the wide toe box give the foot room to move naturally. And because the shoe grows with the foot, it always fits. That matters, because shoes that are too small or too big can affect the way a child walks.

What experts say

Sizeless follows the barefoot shoe principle: a thin, flexible sole, a wide toe box and zero drop. Heel and toes sit at the same height, just like barefoot.

Sizeless starts at size 24. That's roughly the age when children need their first proper shoes. In the first years, barefoot is still the healthiest. When shoes are needed, Sizeless is a good choice because it adapts to the foot.

With a damp cloth, and a little mild soap for heavier dirt. Please no harsh cleaners, no bleach and no hot machine wash. Afterwards let the shoes air dry, not on a radiator or in direct sun.

The shoe is splash-proof, but not waterproof. If it gets wet, just let it air dry.

Because the shoe grows with your child by one full size, you buy new shoes less often. Each pair of Sizeless saves you about one pair of regular children's shoes. That saves material, waste and money.
