Shoe Size Chart and Converter by Foot Length

Each brand converts foot length to its labels its own way. For a 26.2 cm foot, Nike's chart gives US 9 and EU 42.5, Adidas US 9 and EU 42⅔, while Ecco and Birkenstock, European brands, put the same foot in EU 41. The Brands tab shows the size on each chart for your foot length.

Usually not. Nike, New Balance, ASICS and Puma print the shoe's label size in centimeters — about 0.8 cm more than the foot it is made for. Nike's own chart shows both: US 9 is for a foot of about 26.2 cm, while the label says 27. This tool always works in foot length.

By ISO 19407 and the Brannock scale, one size: a men's 9 is a women's 10 for the same foot. Nike, ASICS and Vans print a 1.5 difference, and Converse, Crocs and Skechers 2. For unisex shoes, check the brand's own chart.

They are US width letters: D is the standard men's width (B for women), 2E is wide and 4E extra wide. Each letter is about 3/16 inch (5 mm) of foot width at the same size. European brands mark width with a fitting letter instead — F is medium, G a little wider, H wide.

The insole should be 1–1.5 cm (about half an inch) longer than the foot: roughly half of that lets the toes move forward as the child walks, the rest is room to grow. Much more than that and the child trips. Remeasure every 2–3 months under age three and every 3–4 months up to six.

With the heel against the wall and all four corners of the A4 sheet in the frame, about 2–3 mm. The heel and toe stand above the paper, so the photo only looks for the toe tip near the middle of the frame. For 1 mm, trace the foot with a pencil and photograph the sheet without the foot.

Yes. Take the insole out of a pair that fits well and measure it heel to toe. An adult insole runs about 1 cm longer than the foot, a child's 1–1.5 cm; the Insole mode subtracts that and shows the size in every system.
