Boot sizes and widths

There are nine (9) boot widths in the U.S. boot system. From narrowest to widest: AAA, AA, A, B, C, D, E, EE, and EEE. The D width is considered to be medium for men.

The B width is considered to be medium for women. The widths are separated by 3/16 of an inch, however, the actual width measurement will vary depending on the length.

How to measure your feet to determine your boot size and width.

What you’ll need:

  • Two sheets of paper to trace an outline of your feet
  • Pencil
  • Measuring tape
  • Socks you plan to wear with the boots

How to measure your feet:

Sit with feet firmly planted on the ground.
Holding the pencil perpendicular to the ground, snugly outline your feet.
Measure the widest and longest part of the outline. Subtract 0.2” from each measurement.

Find your boot size below in the corresponding charts.


Take note:
Feet swell and get larger by the end of the day, we recommend you measure your feet in the evening. Your right and left feet vary in size. Use the larger of the two sizes.
