Here are the measurements of our last for every model. You should consider some free space in the front part of the boot.

Usually, we recommend adding 7-10 mm, so for a foot of 27 cm, we recommend size 42. However, if you wear some thicker socks in the winter or if you have very wide feet, you might want to go for the 43.
Some people prefer a tighter fit, and others like it a bit looser.

We found that measuring your feet is the best way that works for everyone. The more precise you can get, the most correct size we can recommend.

HOW TO MEASURE YOUR FEET:

1. Wearing your boot socks, stand on a sheet of paper, and distribute your weight evenly on both feet.

2. Trace carefully around your right foot, creating a single, clean outline, holding the pen 90 degrees with the floor. Repeat this step with the left foot.

3. Measure the tracing length in centimeters from the longest toe to the heel.
