A few helpful details
Good to know
Can I use this for any brand?
Treat the result as a Nike reference only. Always check the size chart for the brand and product you are buying.
Is an EU label a foot measurement in centimetres?
No. Size labels and foot measurements are different. Use the manufacturer’s measuring instructions when starting from foot length.
Where are men’s and children’s sizes?
They are outside this tool’s scope. We show only the adult women’s range described above.
