Tape a sheet of paper to a hard, flat floor.
Stand on it with your weight even on both feet.
Have someone mark the tip of your big toe and the back of your heel, with the pen held straight down.
Step off and measure between the two marks. That is your foot length.
Do the same with the other foot and use the longer one.
Find that length in the foot length column. If you are between sizes, Nike says to go up.

Not at Nike. Nike's chart puts EU 42 at a US men's 8.5 and a US women's 10. A US men's 9 is an EU 42.5.

Take 1.5 off the US women's size. On Nike's charts a women's 8.5 is a men's 7, and the gap is the same on every row.

No. adidas prints one chart for men and women, and on it the gap is one size: a men's 7 is a women's 8.

A US men's 9 or a US women's 10.5 on Nike's chart. It is an EU 42.5.

No. Nike says the cm size on boxes and labels is not the same as your foot length in cm. Measure your foot and use the foot length column.

Every piece on within shows the size its boutique printed and how many are left in it.
