Aerlos Size Guide
Aerlos can run slightly small. We recommend measuring your child's feet and using the chart below, rather than relying on their usual shoe size.
For the best fit, measure your child's foot and compare it with our size chart. Please factor in at least 14mm growing room at the end of the trainer.

How to measure
- Place your child's foot on a flat piece of paper and trace the outline.
- Measure from the heel to the longest toe.
Measure the widest part of the foot for width. - Repeat for both feet and use the larger foot to choose the shoe size.
- Compare the measurements with our size chart below.
