Sidi Socks tend to run slightly large, so ordering down may be recommended. Measure foot according to the chart below, and determine your sock size.
Finding your foot measurements:Trace around the foot, while standing with the feet flat on the floor.
Do this for both feet, as you will use the largest of the two measurements to find your size.
Mark the outer edges, and the top and bottom points of your tracing.
Measure from the top to the bottom to get your size measurement, and from side to side to get the width.
