Introduction of details Size chart HOW TO MEASURE YOUR FOOT SIZE STEP 1: TRACE YOUR FOOT Place a piece of paper on the ground. If your foot is bigger than a single sheet, make it two. KEEP THE PENCIL UPRIGHT (at a 90 degree angle) AT ALL TIMES, especially at the heel. STEP 2: MEASURE LENGTH Use a measuring tape, measure the outline from the back/central part of the heel to the end of the longest toe. ⋙TIPS: 1. For foot length, if you are in between sizes, always move up to the next size. For foot width. choose the width that you are closest to. 2. Trust your own comfort level rather than a shoe's size or description. Sizes vary between manufacturers. 3. Size in men's size, for women's size simply add 1.5.
