Fit Guide
With nearly 100 years of bootmaking expertise, we’ve perfected our craft of turning the details of fit into it a true investment in comfort for your feet. We engineer our footwear lasts, fit adaptations, and construction methods to consider all the anatomical features of the foot, as well as the requirements for various end-use applications. In general, you’ll find all Zamberlan boots to be comfortable – not too long, with a good volume – but the specific fit adaptations below will help guide you to the right boot for your needs.

Size Guide
The foot plays an important role in supporting the weight of the entire body as well as locomotion. The engineering of our lasts and footwear construction take into account all the anatomical aspects of the foot, making it a true investment in your feet. Zamberlan® engineered different lasts based on the anatomical features of the foot and the requirements for various end-use applications.
Generally, Zamberlan boots are all comfortable, not too long and have a good volume.
Boot Lasts & Size Charts
To find your Zamberlan size, measure the distance from the back of your heel to the tip of your longest toe while wearing socks.
- Place a sheet of paper on the floor and trace your foot with your heel against a wall.
- Measure the outline from the back of your heel to the front of your toes.
- Find this measurement in the chart below for the last of your model. If between two sizes, choose the larger.
- Repeat for both feet and use the size that fits your bigger foot.
