GS basically stands for Grade School sizing and today, we’ll be going through what sizes are the best if you’re going to buy a pair to resell. But first, let’s get more in-depth into what it means.

What are GS sneakers?

What does Gs in shoes mean? Gs in shoes refers to Grade School, which is a word for kid’s shoe sizes. However, these are not typical children’s shoe sizes; rather, they are the largest among toddlers and preschoolers. This gives you a way to purchase a pair of shoes for less money.

Give your kids a cutting-edge pair of GS shoes to help them celebrate important occasions while also elevating their look and comfort to new heights.  

For boys, the majority of GS footwear consists of soft and comfy lace-up ankle boots. The majority of them feature a fabric-covered lining and insole. They also feature a sole constructed from premium materials. All of these unique characteristics will undoubtedly satisfy the needs of young children’s foot growth while also providing the optimum stability and freedom for their everyday activities.

Additionally, some manufacturers provide weightless Ecological Leather lace-ups for the GS sizes. All of this contributes to production that is perfectly crafted for kids. However, they can also be very profitable for resellers. 

Now, let’s take a look at a quick size guide for Nike and Jordan shoes.

GS Nike Shoes

The lightweight, static fit of Nike sneakers allows the skin on the feet to breathe. Kids are also given a sensation of speed while they are running or walking.

These GS sneakers contain Zoom Air anti-vibration protection, which provides a flexible and soft feel while maintaining a glittery appearance.

In the United States, Nike sneakers come in sizes ranging from 3.5Y to 7Y. The size categories are between 3 and 6.5, which is not too far from the GS shoe size in the UK.

The GS Nike sneaker promotes skin ventilation since it is made of lightweight, breathable mesh material. Additionally, the cordless design, which is usually covered with fly-wire yarns, provides a solid, precise fit in addition to anti-vibration protection.

Many GS Nike shoes have a shock-absorbing cushion incorporated for comfort when running or jogging. The sloping heel shape ensures a quicker transition from toe to heel and vice versa. 

GS Jordan Sneakers

For children with bigger feet, the Jordan footwear company also offers GS sneakers. There are various aspects of these shoes that set them apart from the adult models from this company, particularly the sizes and styles.

Jordan GS sneakers are in the same size range as Nike GS shoes. For the US size, the Jordan GS shoe size ranges from 3.5Y (Y indicates shoe size for Youth) to 7Y. The UK shoe is available in sizes ranging from 3 to 6.

To reduce the total weight of the shoe and enable seamless transitions, the rubber outsole of Jordan GS sneakers is divided into two pieces. It can switch to herringbone traction thanks to the area of its outsole that is situated just underneath its zoom air unit.

The Jordan GS shoe’s laces also pass straight through a series of interlocking loops and eyelets. Therefore, when you tie your shoes, the pressure you provide to the mesh will help your foot remain steadily on the shoe’s footbed, giving kids that much-needed stability even if they go for a size too large. 

In addition, the shoe has a special tongue composed of breathable mesh, ankle padding, a rubber outer shank, and a logo that changes color. And because of all of these qualities, GS Jordan sneakers are excellent for youngsters to wear to school.

Now, let’s look at a few very profitable GS sneakers and see which size to get for which sneaker model.
