While shopping on StockX, you may have noticed that there are several different classifications of shoes listed on the platform.

And if you haven’t shopped much on the platform, you may not know what each of these abbreviations mean.

In this article, we’ll go over these in detail, as well as share some important tips to ensure you don’t order the wrong shoes!

What Does GS Mean On StockX?

StockX Website

GS stands for grade school, and is one of the sizes that StockX sells. This is associated with the size of an average child’s foot.

Typically, these shoes are made for kids aged 6 and older, though this can vary based on the size of your child’s foot.

GS shoes are gender neutral, meaning that they are suitable for both boys and girls. On some kids shoes, the gender may be specified, but this not applicable to shoes marked GS.

What Does PS Mean On StockX?

PS stands for preschool, and is one of the sizes that StockX sells. This is associated with the size of an average preschooler’s foot.

Typically, these shoes are made for kids aged between 3 and 5. However, some toddlers with larger feet may be able to fit into PS sized shoes.

What Does TD Mean On StockX?

TD stands for toddler, and is one of the sizes that StockX sells. TD shoes are sized to fit the typical size of a toddler’s foot.

TD shoes are made for boys and girls aged between 1 and 3 years old, and the sizing is gender neutral.

What Does I Mean On StockX?

I stands for infant, and is the smallest size that is sold on StockX.

These are made for infants and babies under the age of one. Because there is no much difference in the foot structure between baby boys and baby girls, infant sizes are gender neutral.

A Brief Recap

To quickly recap, here is what each abbreviation means on StockX:

  • M: Men’s Sizes
  • W: Women’s Sizes
  • GS: Grade School, Ages 6+
  • PS: Preschool, Ages 3-5
  • TD: Toddler, Ages 1-3
  • I: Infant, Age 1 or younger.

Use this for reference, and you can be sure that you’re ordering the right shoe size for your use case!

Note that different brands and manufacturers size slightly different – so a GS size 8 Nike Air Jordan shoe might fit differently than a GS size 8 Adidas shoe, for example.

What Happens If I Ordered The Wrong Size?

Unfortunately, StockX does not allow for returns, refunds or exchanges if you ordered the wrong size of shoe on their platform. However, you may be able to cancel your StockX order if you’re lucky.

This is to keep things fair for other buyers, as well as sellers. Because they are a marketplace and prices can change at any time, their strict return policy keeps things fair for everyone.

However, you can relist the shoes back on StockX for their current market value. Note that because there are multiple steps in StockX’s shipping and verification process, the price can change from the time you’ve ordered them to the time they’re actually received.

When ordering shoes on StockX, always be sure that you’ve double checked the size – not only the number, but the correct classification as well.

If you’re a man ordering for yourself, double check that the shoes being ordered are in Men’s sizes.

Why Are GS Shoes Cheaper On StockX?

GS shoes tend to be cheaper than men’s shoes or women’s shoes, due to lower manufacturing costs associated with the order, and competitive pricing. GS shoes may also use lower quality materials and may not be as durable – this may be a design choice, as kids tend to outgrow shoes quickly.

It’s common that shoes made for kids are cheaper than their adult counterparts, even factoring in the same design, brand and model.

However, that doesn’t mean that you’re getting a deal.

We’ve heard stories of people ordering GS shoes on accident because they believed they were identical to men’s shoes, only to discover that they were stuck with shoes that they could not wear.

While StockX doesn’t allow returns for incorrect sizing, you can relist the GS shoes on StockX for the current market price – likely regaining most of what you paid for them.


GS, PS, TD and I are all various abbreviations used to describe the size of shoes that you’re ordering.

Make sure that you’re ordering the right size, because StockX does not offer refunds if you purchased the wrong product by mistake.
