Sizing

All of our shoes are in US sizes. In general, the US size is one up from the UK size (ie UK 5 = US 6) but please measure your child's foot and use our sizing chart to ensure a correct fit.

IMPORTANT: When reading the sizing charts below please remember that the 'length' refers to the inside length of the shoe, NOT the foot.

For example, the length of of US 5 shoe is 13.1 cm. Therefore, if your child's foot is 13 cm you will need to order a size US 6 to allow for growing room. 

Always measure your child's foot before ordering. Remember, sizing varies between brands so a size US 5 in our shoe may not be the same as a US 5 in another brand.

Select the correct range for your child. If your child is not yet walking the Smaller range (0-6 months ot 18-24 months) is primarily an indoor shoe.

If you need a shoe for outside crawling/ daycare we recommend the See Kai Run range (leather shoes and sneakers, sizes US 4 to 9) as shoes in the See Kai Run range are suitable both as a pre-walker and a first walker.

If your child is around two years old and is a size US 8 or more then the Kai range (US 8 to US 13 in child sizes and adult/youth 1 to 3) is often a better fit. The Kai range is a slimmer fit than the See Kai Run range.

If you are unsure about sizing please call us on 1300 249 849.

Printable Sizing Chart

Click here to print the sizing chart  for Smaller, See Kai Run and Kai.

Make sure you print the chart out at 100% for accurate sizing.

'Inside length' on the sizing chart refers to the inside length of the shoe, not your child's foot.

Please allow 0.5 to 1 cm growing room when using this chart. For example, if your child's foot sits on or just under the US 4 size line, you will need a size US 5 to allow for growing room.

How to Size Your Child's Feet:

  • Have your child stand on a piece of paper on a firm surfance.
  • Ensure your child is standing in their usual walking position (the same angle of the feet and distance between feet), standing upright and bearing equal weight on both feet.
  • Mark the longest points of the foot, from the longest toe to the back of the heel. Measure this distance in centimeters to get the length.
  • NOTE: When making the heel mark make sure you angle the pen straight down from the top of the heel which is the widest part.
  • Allow .5 - 1 cm extra when selecting shoe size, more if the child will wear thick socks with the shoes.
  • Measure often - children's feet grow quickly. Measure at least every 2 months during the first year, and every 3 months from 1 - 3 years. You never can tell when your child will have a growth spurt!
