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 which will not follow standard sizing:

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.

Please also note that sizes between brands will fit differently. For example, a size 8 Adidas will not fit the same as a size 8 Nike.
