How To Determine Your Size & Width Using The Sizing & Width Measuring Tool:

  1. Remove your shoes, but be sure to leave on a pair of socks similar to the type that you plan to wear with your shoes.
  2. Put a straight edge (ruler, clipboard, book, etc.) on the red line behind where it says "Right/Left Heel" (depending on which foot you are measuring--using the correct side is VERY IMPORTANT).
  3. While standing, put your heel firmly against the straight edge and put your foot down.
  4. Record the size indicated at the tip of your longest toe (the longest point of your foot). Marking this with a pen while standing on the tool is best, as it can be difficult to accurately read the measurement from a distance. If the size falls between two lengths, choose the longer length.
  5. Repeat entire measuring process for your other foot, but remember to flip the measuring tool so that you are using the correct side: Right or left heel. Very few people have feet that exactly match one another, and you should buy shoes based on your larger foot size.

Now that you know your size, print the corresponding WIDTH measuring tool and follow steps 1 thru 3 ABOVE, then continue below:

  1. Record the width indicated on the widest part of your foot (make sure that the inside of your foot is properly aligned with the red line). Marking this with a pen while standing on the tool is best, as it can be difficult to accurately read the measurement from a distance. If your width falls between two widths, and you prefer a closer fit, you may want to stick with the narrower width unless you have a high instep. If you prefer a looser fit, go with the wider width.
  2. If you are a "2E" make sure that you buy half a size bigger than what you measure. So if you are a size 10EE, buy a size 10.5E.
  3. If you are a "3E" make sure that you buy a full size bigger than what you measure. So if you are a size 10EEE, buy a size 11E.
  4. If you have a high instep, you should stick with one of the lace shoes or monk straps. If you have a VERY high instep, go up half a size (if you are a "D" width with a very high instep, get an "E" width in your proper size).
  5. If you are a "C" width, make sure that you buy a half size smaller than what you measure. So if you are a size 10C, buy a size 9.5D. You should also stick with a lace shoe so that it can be better adjusted to your foot.
  6. If you are a "B" width, make sure that you buy a full size smaller than what you measure. So if you are a size 10B, buy a size 9D. You should also stick with a lace shoe so that it can be better adjusted to your foot.
