GS or Grade School means that those shoes are fit for young kids aged 8 to 12. Whereas those shoes with a big K indicate that they are fit for much older age, perhaps high schoolers and adults.

What does GS mean in shoes?

Here is the answer. Gs in shoes stands for Grade School, which is a term of shoe sizes that is used for children. However, they are not the normal children's shoe sizes; these sizes are the biggest ones among preschool kids and toddler's shoe sizes.

Can adults wear GS shoes?

This is because children feet are in the growth stage, due to which shoe brands do not put extra material in making children or big kids shoes. So, as an adult, you can wear gs size shoes for casual walks. But, don't try to run in them as you'll end up hurting your feet and damaging the shoes.
