Fit of children's shoes
The human foot takes approximately 18 years to fully develop. Of course, it grows fastest in the beginning. Therefore, you parents should check the fit of your children's shoes every 3-4 months. For POLOLO street shoes, we have always developed removable soles - as far as this was possible for the respective style. On the one hand, you can easily replace a sole (e.g. add a wool sole for the winter) and you can use it to measure the foot length and fit very well. If the imprint of the big toe is already dangerously far forward, then your child has already grown again and is due for the next shoe size. Our soles are all very flexible, especially our Barefoot collection.


POLOLO pursues the highest ecological standards
When producing our POLOLOs in Spain, we pay great attention to ecological, pollutant-free materials and workmanship throughout the entire production chain. We only use German natural leather that is vegetable tanned and certified, organic quality cotton (organic / kbA) and wool from controlled organic animal husbandry (organic / kbT). POLOLOs are allergy-friendly and therefore our leathers are naturally chrome-free.
