Measuring Your Feet
Always measure your feet wearing socks unless the style is made to be worn with bare feet. Use your largest foot to take the measurement, and if unsure, measure both and use the larger measurement.
What you’ll need: A ruler or tape measure, a pen and a blank piece of paper (A4 or larger)
Place the short end of the paper against a wall. Place your largest foot on the paper with your heel against the wall, so that your heel is equal with the edge of the paper.
Without moving your foot, use the pen to mark where your longest toe ends. Step off the paper.
Using your ruler or tape measure, measure from the edge of the paper to the line you have drawn. You can now use this measurement to determine your shoe size.
If your new shoes aren’t quite right, we welcome you to take advantage of our generous Returns Policy.

Measuring Your Child's Feet
Always measure your feet wearing a sock, unless the style is made to be worn with bare feet. Grab a seat, then place a piece of paper in front of you. Use a pencil to trace around your foot. Ensure you hold the pencil as straight up as possible whilst tracing and ensure the pencil remains in contact with your foot during the process. With a ruler measure the distance between the base of the heel and the tip of your big toe. This distance is your foot length and is the number you use to determine your shoe size.
This chart should be used as a guide only. Due to each manufacturer’s size scale inconsistencies may occur.
If you do order the incorrect size you may be able to return items in accordance with our returns policy.
