To get a proper fitting running or hiking shoe it is important to get your foot measurement and then understand how a running shoe should fit and how to check the fit.

 

How to measure your foot

Use a piece of paper or card larger than your foot, a tape measure or a ruler, a straight edge and a pen or pencil.

Draw an outline of your foot to measure the length

Measure the length and width of both foot outlines

 

Your running shoe size

While running, your feet lengthen and widen when the foot/shoe contacts the ground.

This happens with each step and the foot returns to its normal length and width when the foot/shoe is off the ground.

We recommend your standard running shoe size should be the next half size longer than your measured size.

Your standard running shoe size is typically a half size larger than your dress/casual shoe size.

If you have measured your foot on a Brannock or other foot measuring device, this half size larger rule still applies.

 

Get your shoe size

Sizing may well vary between shoe models, even from the same manufacture and brand. The variation is due to the construction process of making the shoes and attaching the upper to the midsole.

 

Shoe Fit

A proper fitting shoe should be snug in the heel and midfoot area to keep the foot in place. Feet expand during a run and so a proper fitting shoe should have room around the toes to allow for this.

To determine the proper size shoe for you consider the following:

True-to-size: A shoe that should fit according to the value obtained from the industry standard Brannock Device is said to fit true-to size.

Half-size small: A shoe that fits a half-size smaller than the value obtained from a Brannock Device. So if your foot is measured at a size US 9, you will need to get a size US 9.5.

Full-size small: A shoe that fits a full-size smaller than the value obtained from a Brannock Device. So if your foot is measured at a size US 9, you will need a size US 10.

Length: If you are not measured with a Brannock Device, use the method above to measure your foot or find a hard, flat floor and place your heel against a wall and measure the length of your foot. 

Use the charts below to convert your measurement to a shoe size.

Note the difference in sizes for women's and men's shoes for the same length of foot.
