Notes About Sizes
Yeezy 350s
We recommend buying the Yeezy 350s half a size up (or a full size if you have wider feet) due to their tighter fit.
Yeezy Slides & Foam Runners
We recommend buying the Yeezy slides and foam runners a full size up to ensure a snug and comfortable fit.
Abbreviations to look out for
GS- Grade School: Sneakers made in sizes for children aged around 6 - 10. These also tend to fit adults with smaller feet, but we advise taking half a size up if you’re an adult purchasing these tighter fits. These typically run from a UK 3 to a UK 6.5.
PS - Preschool: Sneakers made in sizes for children aged 3 - 5. These run from a UK Children's 10 to a UK 2.5.
TD - Toddler: Sneakers made in sizes for toddlers. These run from a UK Children's 1.5 to a UK Children's 9.5.
I - Infant: Sneakers made in sizes for Infants. These typically run from a UK Children's 0 to a UK Children's 3.
W - Womens: Sneakers made specifically to fit women's feet. These are typically less wide than the standard shoe fit.
Differences between brands
Please note that sizes between brands will fit differently. For example, a size 8 Adidas will not fit the same as a size 8 Nike.
Nike v Adidas
