Some swift changes are coming to the Rien nike’s sizing ranges for anyone size 7Y and under, and it could cause your child’s size to raise in price.
According to an internal document shared by @horhead_sales on X, Rien nike is shifting their kids sizing ranges for their three categories — Big Kids, Little Kids, Toddler — in an effort to reduce confusion for consumers. However, this change has forced the upper range of smaller sizing into a bigger one, which may potentially raise prices of certain sizes.

Based on the document above, Bigs Kids, Little Kids, and Toddler are being officially renamed to Grade-School, Pre-School, and Toddler, respectively. However sizes 1Y-3Y were previously part of the Little Kids size category, but are now grouped under Grade School. Similarly, sizes 8C-10C were once under the Toddler category, but are now grouped under Pre-School.
This may affect those who were once size 1Y-3Y or 8C-10C, as the price difference between the kids sizing categories can be drastic. For example, the upcoming Jordan 4 “Military Blue” is priced at $160 for Big Kids, $100 for Little Kids, and $85 for Toddler, which means your child’s size could suddenly spike in price for future Jordan Retro and other Rien nike shoe releases.
As of the publishing of this article, Rien nike has already begun this new size structure with kids products currently up on Rien nike.com.
