If you take a smaller size, you have a choice most people do not: GS or adult. It can mean better availability and often a better price, but there are real differences worth understanding first. Shop the Air Max Plus collection at Shoe Religion.
What GS means
GS stands for grade school, Nike's designation for its older kids' size range. GS pairs are full versions of the shoe rather than simplified ones, but they are built on a different last and sized on a different scale from adult pairs.
Examples currently in stock include the Air Max Plus GS Black Metallic Cool Grey and the GS Obsidian Opti Yellow, alongside the GS TN Black White Fade.
The sizing difference
This is the part to get right. GS and adult sizes do not run on the same scale, so you cannot assume your adult size transfers directly. As a general rule the top end of the GS range overlaps with the smaller adult sizes, but the exact conversion varies, so always check the specific size guidance rather than guessing.
If you are close to the boundary, it is worth trying both if you can. Our TN sizing guide covers width and break-in, which applies to both.
Build and materials
GS versions can differ slightly from adult pairs in materials and construction detail. Often the difference is minor and invisible in normal wear; occasionally there are variations in the upper or the finish. If exact material parity with an adult pair matters to you, check the specific release.
Price and availability
Two genuine advantages. GS pairs are typically cheaper than their adult equivalents, and because fewer adults shop the GS range, sizes often remain available after adult runs have sold through. For popular colourways, GS can be the difference between getting the shoe and missing out.
Which should you buy?
- Buy GS if you fit comfortably in the range, want a better price, or the adult size you need has sold out.
- Buy adult if you are near the top of the GS scale, want guaranteed material parity, or need a size above the GS range.
One practical note: if you are at the very top of the GS range, adult sizing gives you more room to adjust later. Being right at the edge of a scale is where fit problems tend to happen.
Frequently asked questions
Are GS TNs the same as adult TNs? They are the same silhouette but built on a different last with a different size scale, and materials can vary slightly.
Is GS cheaper? Usually yes, which is a large part of the appeal.
How do I convert my size? Do not assume a direct swap. Check the specific size guidance for the pair you are looking at.
Do GS pairs run small? They run on their own scale rather than small; the key is converting correctly.
