Sizing Information

Get The Right Size The First Time!

Having to return a new pair of shoes because the size is wrong is the worst! We put together this short video to show you how to best use our sizing guide so that you can select the correct size the first time. Download the sizing guide below the video.


If you are unsure of what size to select, please take a photo of your foot (or your child's foot) on the foot on the sizing guide and send it to support@splayathletics.com.

If you prefer to measure your child's feet, you can do so and compare it to the sizes in the chart below. Be sure to leave some growing room. Ideally, it is recommended that you leave at least 3/8 inch (1 cm) and no more than 3/4 inch (1.9 cm).
