Footwear fitting guide


Please Order In Your US Size

It's an amazing fact, but one in three women in the US don't know their true shoe size. We all know our shoe or boot length, ie size 6, but there are two other important measurements to achieve a perfect fit. For shoes and boots you need your foot width, and for boots you also need your calf width. Follow these three simple steps to find out both, and discomfort caused by badly fitting footwear will become a thing of the past.

Step one

Choose your regular shoe size

Step two

Measure the circumference of the widest part of your foot using a tape measure.

Using the below chart, choose your regular shoe size on the left, and move along the chart to your foot width measurement.

Then follow the chart up to find your width fitting.

EXAMPLE: If you are a US size 8 and your foot width is 9 3/4 inches, then your foot width is EEE fit, so you will order a US 8 EEE Fit

Foot Width (Inches)
US Shoe Size D Fit (Standard E Fit (Wide) EEE Fit (Extra Wide) EEEEE Fit (Ultra Wide)
US 5 8 1/4 8 1/2 9 9 1/2
US 6 8 1/2 8 3/4 9 1/4 9 3/4
US 7 8 3/4 9 9 1/2 10
US 8 9 9 1/4 9 3/4 10 1/4
US 9 9 1/4 9 1/2 10 10 1/2
US 10 9 1/2 9 3/4 10 1/4 10 3/4
US 11 9 3/4 10 10 1/2 11
Foot Width (Millimeters)
US Shoe Size D Fit (Standard E Fit (Wide) EEE Fit (Extra Wide) EEEEE Fit (Ultra Wide)
US 5 210 216 228 241
US 6 216 222 234 247
US 7 222 228 241 254
US 8 228 234 247 260
US 9 234 241 254 266
US 10 241 247 260 272
US 11 247 254 266 278

Step three

Measure the widest part of your calf using a tape measure.

Using the below chart, choose your shoe size on the left, and move along the chart to your calf width measurement.

Then follow the chart up to find your width fitting.

EXAMPLE: If you are a US size 8 EEE and your calf measurement is 19 1/2 inches, then your calf width is Super Curvy, so you will order a US 8EEE Super Curvy Boot.
