Men's Shoes
Wear the type of socks you'll wear with your shoes and measure feet in the afternoon (feet typically swell during the day). Distribute weight evenly before measuring.

STEP 3
 | 
| 
 Stand up straight on a hard surface with your heel against the wall and a piece of blank paper taped to the floor, flush against the wall beneath your foot. 
 | 
 Have someone mark the longest part of your foot (referred to as heel-to-toe length) on the paper with a pen or pencil, or measure yourself if necessary. Repeat with the other foot, as right and left sizes may be different. 
 | 
 Use a ruler to measure the heel-to-toe length you marked for each foot.

Step 2: Find Your Size
