Tips:

1.  Take your measurements in the afternoon, when feet tend to be their largest.
2.  Wear the same socks or stockings that you will wear with your new shoes. Example: barefoot for sandals, thick socks for winter boots.
3.  Some people have one foot slightly longer/wider than the other. Measure both feet, and use the longest and widest measurements to fit your shoes.
4.  Don’t assume your shoe size is the same as it always has been. The shape of your feet changes over time.
5.  Insole length may be slightly larger than your foot length, especially with pointy toe shoes.
6.  Shaft circumference and height vary with size. Their interval between sizes is about 0.2″ (0.5cm).
7.  There may be 0.8″ (2cm) deviation because of manual measurement.
8.  Some shoes are given recommendations to order smaller or larger (e.g. runs narrow; order 1/2 size up).
9.  If half sizes are not available, order a full size up.
10.  If you have narrow feet and a narrow-fit isn’t offered, consider going down a half-size if possible.
11.  If you have wide feet and a wide-fit isn’t offered, try going up a half size to create more room.
12.  If you don’t know your size in athletic/running shoes, consider ordering a half size larger than your normal size
