StockX lists all sneakers in US sizing, and a size chart is available on each product page. For brand-specific fit recommendations or gender size conversions, contact the manufacturer directly (such as Nike or Adidas). Review any sizing abbreviations or fit notes on the product page before placing an Ask or Offer.
Sizing abbreviations

Common sizing abbreviations on StockX:
- (W) – Women
- (GS) – Grade School
- (PS) – Preschool
- (TD) – Toddler
- (I) – Infant
- (Infant)
- (Kids)
- (Asia Sizing)
Wide sizing
Some sneakers (primarily New Balance) are available in standard and wide fits. When a wide fit option is available, "WIDE" appears next to the size number.
Asia sizing
Items released in Asia-specific territories may vary in sizing. These items include "(Asia Sizing)" in the product title.
