Get Fit

We recommend measuring your feet at home by following these easy steps:

What you will need:

• Pen/Pencil
• Paper
• Ruler/measuring tape

1. Place the piece of paper under your foot and stand with your heel against a wall
2. Trace your foot as closely as possible
   (Be sure to trace both feet, as one foot is often longer than the other)
3. With the tracing measure a straight line from the back of the heel to the longest toe
   (This will give you the length of your foot in centimetres)
4. Add 1-1.5cm to this measurement to give you the most accurate length for your shoes
5. Take this total measurement in cm and using our international sizing chart match it to your US size.
