Free Offers
Free Activities for Children and Families
During our pop-up store, we want to create a small meeting point for families in the neighborhood. That's why we regularly offer free activities for children and parents.
You can look forward to playgroups, reading sessions, and parent-child movement classes, among other things. The activities are child-friendly, uncomplicated, and open to families from Cologne and the surrounding area.
The activities will take place during the period of our pop-up store. Feel free to stop by, bring your children, and enjoy a wonderful time with us in Sülz.
About Sizeless
Children's shoes that grow with them
We are Sizeless, a Cologne-based startup with a simple idea: children's shoes should fit longer.
Many parents know the problem: no sooner are new shoes bought than they are already too small. That's why we have developed a children's shoe that can be adjusted to the exact millimetre in size.
The idea for Sizeless originated as a student project at the German Sport University Cologne. From initial prototypes, conversations with parents and a lot of development work, our first growing children's shoe was created.
Our goal is to make shoe shopping easier for parents and to give children shoes that fit their growing feet better.
Now you can experience Sizeless live in Cologne for the first time.
