Fit Tips

Footwear that is too small are one of the major causes of foot pain and problems
Footwear that is too large can cause blistering and a lack of stability
Don't assume your foot size is the same as it always has been. The shape of your feet changes over time.
Not all brands of footwear fit the same. The below generic size guide is a good indicator on what footwear size you should wear, but some brands may offer slightly different sizing guidelines.

Take your measurements at the end of the day, when your feet are the largest
Wear the socks you'll wear with your new footwear when you measure
Measure both feet and fit shoes to the larger foot
If you are doing the measurement by yourself, you will get more accurate results if you sit in a chair when measuring, i.e. don't stand.
If you have someone to help you take your foot measurement, standing is the best choice

While seated, place your foot on a piece of paper in front of you
With a pencil, trace around your foot. Hold the pencil as straight up-and-down as possible while measuring and ensure your pencil remains in constant contact with your foot while tracing around it.
With a ruler, measure your tracing to determine your foot length (the distance between the two longest points on your tracing. Reduce this number by 5 mm. The result is your foot length and the number you will use to determine your shoe size.
