Women's = men's + 1.5 for most brands (Nike, Jordan, New Balance). adidas is usually men's + 1.
Youth (Y, GS) sizes match men's sizes up to 7Y, so a 7Y fits like a men's 7.
Fit varies by model, so check the product description for notes like "runs small". All sales are final, so if you're between sizes, message us before you buy.
Sizing questions
I'm between sizes. What should I do?
Check the product description for fit notes (some models run small). If you're still unsure, message us on Instagram or TikTok before you buy: all sales are final.
What does "GS" or "PS" mean?
GS (grade school) are big-kid sizes, labelled Y (3.5Y to 7Y). PS (preschool) are little-kid sizes. They're in the product name when they apply.
