Extended Sizing
Definition
Sizes outside the standard range, such as very small (below men's 6) or very large (above men's 14). Extended sizes are harder to find and may command higher resale prices due to limited production.
In Context
“If you wear a size 15 you know the struggle — extended sizing pairs are rare and the resale premium is real.”

More Sizing Terms
True to Size (TTS)
A sneaker that fits as expected based on your standard shoe size. When a shoe runs TTS, you can order your usual size with confidence.
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.
