Shopping questions
GS is commonly used for Grade School editions, and PS for Preschool editions. They identify children’s product categories rather than a single shoe size. Choose using the complete size label on the exact product, including its UK, US and EU information.
Children’s UK sizes run through the smaller-size sequence before starting again at 1. A preschool UK 11.5 is therefore very different from an adult UK 11.5. In this edit, the Jordan 11 PS listing shows that children’s size with US 12C and EU 29.5.
Nike children’s US labels can include C and Y. Keep those letters when checking a product or asking for help. A bare number copied from a different brand or an adult listing is not enough to identify the same option.
Measure both feet and work from the longer measurement when using the relevant size guidance. The child’s age alone is not a reliable way to select a size. Check the product’s complete size label and any fit information before ordering.
This edit separates PS and GS examples, including both casual trainers and a junior running model. Use the product description to choose the intended activity. If a conversion or repeated UK size is unclear, contact us with the product code and full variant label before buying.
Choose a product to check the available sizes, current price and full details. Stock is specific to each size.
