More Sizing Terms
Half Size Up
A recommendation to buy a sneaker half a size larger than your normal size. This is common for shoes with narrow builds or snug knit uppers like Yeezys and Flyknit models.
Half Size Down
A recommendation to buy a sneaker half a size smaller than your normal size. Some sneakers with roomy fits or stretchy materials may require going down for a snugger fit.
Wide Foot
A foot shape that is broader than average, requiring sneakers with more room in the midfoot and toebox. Brands like New Balance are often recommended for wide foot wearers.
Narrow
Describes a sneaker that fits tightly side to side. Narrow-fitting shoes can be uncomfortable for those with wider feet and may require sizing up for a better fit.
GS (Grade School)
Youth sizing for older kids, typically ranging from 3.5Y to 7Y. GS sneakers are popular among smaller-footed adults as a more affordable alternative to men's sizing.
PS (Preschool)
Sizing for younger children, typically ranging from 10.5C to 3Y. Preschool sneakers are scaled-down versions of adult models with kid-friendly closures.
