Nike to lululemon shoe size

The short answer

Nike 7.5 is lululemon 8 by the two brands' own charts. 8 of 13 Nike sizes land on a different label at lululemon.

Both brands publish the foot length each size is built for, so every row matches a foot, not a label.

On 3 sizes the charts land two or more sizes from the same label. Brands do not measure the body the same way, so on those rows treat the chart answer and the same label as the two ends of a range.

Every Nike size read across to lululemon. US women's sizes on the left, US women's on the right.
