How do I determine my size?
To measure your foot length, stand on a leveled floor with the back of your heels against a straight edge or wall. Measure your foot length by placing a ruler flat on the floor straight alongside the inside of your foot from your heel to toes. Place an object with a flat edge straight across your toes with the edge touching the tip of your longest toe. Take the measurement from the ruler where the flat edge crosses. This is your foot length measurement.
Tip: Do this preferably in the afternoon, when your feet are tired and tend to swell up a bit.
