GS in shoes usually means “Grade School” — a size category for kids, especially school-aged children. It’s common in sneaker lines from brands like Nike and Jordan, and GS pairs are typically smaller than adult sizes and may be priced differently.

Quick Scoop

  • GS = Grade School. It refers to youth sizing rather than adult sizing.
  • Typical range: many brands use GS for roughly US 3.5Y to 7Y.
  • Not just for girls: GS is generally unisex , despite some people assuming it means “girl size.”

If you want, I can also explain how GS compares with PS, TD, and men’s/women’s sizing.
