Sizing Information


***The sizing of our shoes has changed with the release of the Splay Loco. The new sizing should run more true to size. The Loco runs nearly a full size smaller than our original shoe. So if you were a 2Y in the original shoe, it is likely that you would need a size 3Y in the Splay Loco. Please print the new sizing guide below and remeasure to ensure proper fit.***

Get The Right Size The First Time!

Our printable sizing guide will help you get the right size the first time. Simply download the guide below, print it off, and measure your child's feet. Ensure that "Fit To Page" or "Shrink To Fit" is not checked as it must be printed at 100% scale.
The lines on the guide show the actual length of the inside of the shoe. 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). 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 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.
