Between sizes? Choose the next size up if your foot measurement falls between two sizes or is at the maximum length shown.

Measure Your Feet

Measure in the socks you normally wear with your shoes, or barefoot if that is how you plan to wear them.

1. Stand at a wallPlace your heel against a wall with your foot flat on the floor.
2. Measure to your longest toeMeasure from the wall to the tip of your longest toe. Keep the tape straight.
3. Repeat on both feetMeasure your other foot and use the longer measurement when checking the chart.

Example: If your foot measures 22.5 cm, choose EU 36, which has a maximum foot length of 23.0 cm.

Fit & Insoles

Duckfeet shoes have a naturally wide fit and a flat leather footbed.

Toe roomYour toes should move freely and should not touch the front of the shoe while walking.
Leather fitThe natural leather softens and stretches with wear, especially across the width.
Wool-lined stylesWool-lined boots can feel tighter. Consider extra room for the lining when choosing a size.

Insoles: Wool insoles can help create a closer fit. If you prefer additional arch support, consider an insole designed for that purpose.
