How Our Site Sometimes Shows Sizes
You may notice sizes on our site that look like "85" or "100" - here's what that means:
-
"85" = Size 8.5
-
"100" = Size 10.0
We’re currently working on standardizing all sizing labels, but in the meantime, if you’re unsure what a size means, just chat with us, we're happy to help!

| KID'S | 4 | 5 | 6 |
