Dirty wellies can easily be washed on the outside with clean soapy water. Over time, natural white stains can appear – these can be washed away.

If the wellies gets wet on the inside, the best way to dry them is to fill them completely with small crumpled newspaper balls. The balls must be changed several times until the boot is dry.

TIP! You can extend the life of the boots by storing them in a dark and cool place.


It is important that you measure your children’s feet regularly, as small feet grow quickly. The size can change from month to month. In general, children’s boots should be 1 – 1½ cm longer than the foot.

What size?

  • Always count on 1 – 1.5 cm in growth allowance.

  • The size of wellies and boots may vary by a few mm between the different boot types.

Time to change size?

The child’s foot must have room to slide forward when the child walks. Therefore, switch to the next size when there are about 5-7 mm left.

How fast do childrens feet grow?

  • 0-2 years approx. 2 cm per year

  • 2-6 years approx. 1½ cm per year

  • Over 6 years approx. 1 cm per year


How often should the foot be measured?

  • 0-2 years – every 2 months

  • 3-6 years – every 3 months
