• Measure around the forefoot at the widest part, just behind the toes, in a similar place to where the arrows are on the photo – a piece of string works well and can be laid flat on a ruler to get an accurate measurement.
• Half this number and call it measurement A
• Repeat the process around the mid foot – just behind the ball of the foot where the elastic top of the foot-thong would sit.  This will help make sure the elastic top will be a comfortable fit.
• Half this number and call it measurement B.
• The resulting numbers can be used on the following chart to (hopefully) help select the right size foot thong.

Please remember that all sewing and measurements have been done by hand so  some small discrepancies should be expected.
