A pair. Instead of three per year.
Children's feet grow up to 1 mm per month. Conventional shoes, therefore, only fit for a maximum of 2–3 months – after that, you have to buy new ones.
Sizeless can be adjusted continuously by 8 mm, roughly one shoe size. A pair can accompany your child for up to 9 months. No need to buy new shoes in the middle of the season.
The stepless size adjustment means we don't have to constantly buy new ones. This makes our everyday life noticeably more relaxed.
