How to measure your feet

If you’re unsure which shoe size you are, follow these simple steps.

Measure at the end of the day when your feet are at their largest.

  • Tools: ruler, pen, and a piece of paper.
  • Tip: Measure at the end of the day when your feet are at their largest.

Step 1

Place the paper on the ground and stand on it with your weight slightly forward to make sure your foot is flat.

Step 2

Draw a line behind your heel and another line in front of your longest toe. It is common to have one foot longer than the other, so use the longer foot to measure.

Step 3

Measure the distance between lines in inches or centimetres. Find your measurement on the Muck Boot size guide to figure out the best. Round up if your size falls in between.
