What is Grade School (GS)?
Grade School or GS refers to the reengineered sizes of popular sneaker silhouettes.
Built of a smaller and narrower construction, Grade School models are specifically designed to fit a foot smaller than the average male, offering the perfect fit for girls and adolescents. As standard men’s sizes commonly start at US 7, Grade School sizing fits a smaller male’s foot perfectly.
Often referred to as Youth Sizing, models are marked with a ‘Y’ symbol/lettering. Grade School sizing applies specifically to Nike & Air Jordan models, and is available from US 3.5Y to US 7Y.
