Material:

Upper: Leather with waterproof TEX membrane (Smooth leather at the bottom and suede higher up)
Lining: 100% soft wool
Insole: Removable wool insole with an aluminum underside to keep cold away
Outsole: TPR rubber. The sole extends all the way up to the toe box, protecting the shoes from scratches during the child's active play.

The Acquastop membrane is positioned between the outer and inner lining, keeping moisture out while allowing breathability.
What we love about these shoes:

Low shoe weight
Wide toe box
Flat and flexible, thin sole
Warm wool interior
Quick lock at the top for easy dressing
The perfect pair of warm winter boots for toddlers with a high shaft that protects against snow

Fit and size advice:

Fits narrow to normal width feet
Fits low to normal height feet - this model is not the best for a high and chubby child's foot.
Slightly small in size. Check the size chart below

Lining: Warm wool lining. To make the shoes extra warm, add a wool insole.
Care instructions: Clean dirt by wiping with a damp cloth.
Note! Bundgaard recommends spraying the shoes thoroughly 1-2 times before use, and then regularly as needed. Use, for example, Collonil Protect & Care shoe spray, to keep the leather soft and improve resistance to moisture and dirt.

Size chart
To choose the right size, measure the child's foot by placing the heel against a wall and measure up to the longest toe. Add 1.2-1.7 cm to this foot measurement to get the right size according to the chart below. We have verified the shoe measurements, but it is difficult to get them exact to the millimeter as the shoes have some give when measured. If you're between two numbers, choose the larger option.
