What is 'GS' Sizing?

What does GS mean? - Sneakers with 'GS' in the name are made for 'Grade Schoolers'. These tend to fit smaller and we would advise adults to take half a size up your normal UK shoe size. These run from a UK 3/EU 35.5 to a UK 6.5/EU 40. This will workout a cheaper option for you, as GS sneakers are also smaller in price compared to Adult sneakers.
