How to measure shoes size

Tips: 

Measure in the evening, when the foot is at its fullest shape
Be barefoot or put on socks that you plan to wear with the new shoes
Stand on a hard surface

ask a friend to help you stand straight with your weight equally distributed on both legs trace both feet because it’s normal for one to be longer than the other

measure the distance between two most prominent points (from back of the heel to the end of the longest toe) write down the numbers you get use measurements of the longer foot
