1Measure Your Foot

Stand on a piece of paper with your heel against a wall. Mark the tip of your longest toe, then measure the length in inches or centimeters.

2Find Your Size

Match your foot length to the table above. If you are between sizes, we recommend ordering the next size up for thick socks.

3Check the Fit

There should be about a thumb's width of space at the toe. Boots should feel snug at the heel without slipping.

4Mind the Calf

For pull-on styles, measure your calf circumference at the widest point and compare it to the calf measurement listed on each product page.

Fit Tips

Most waterproof boots are designed to be worn with thick socks, so a slightly roomy fit is normal.
If you usually wear a half size, size up for insulated or winter styles.
All measurements are approximate; small variations can occur between different boot styles.
For work boots featuring a steel or composite toe, always try them on with the socks you plan to wear on the job.
