Independent brand size reference
Use Nike's current product or footwear chart for the exact item. This independent guide explains how to measure and read its columns; it is not a complete Nike shoe, apparel, or kids size table.
Measure the relevant body part or longer foot, select the official table for the exact product and audience, then compare the measurement with the column named by that table. Do not treat this independent guide as a complete brand chart.
Brand-specific sizing advice that goes beyond the standard chart.
Start with the current Nike chart for the product and audience you are buying; do not transfer a label from an older or different model.
Compare your measured longer foot with the chart's Foot Length column. A CM/JP label is a separate label column, not automatically your measured foot length.
If a product listing offers a width or fit note, use that note before changing length; extra length is not a substitute for an available width.
This page covers how to read Nike’s footwear sizing information. It does not reproduce a complete Nike table, prescribe a fit outcome for a whole model family, or provide an apparel or children’s conversion rule. Nike can change regional ranges and product notes, so the official chart linked above is the source for a current purchase.
Measure both feet while standing on a hard floor, wearing the socks you plan to use. Record heel-to-toe length in centimetres and use the longer result. Compare that number with the Foot Length column on the relevant Nike chart.
Do not assume that a column labelled CM or JP is the same measurement. On Nike’s men’s chart, US 10 has Foot Length 27.1 cm and a CM/JP label of 28. The label and the measured foot length are related chart values, but they are not interchangeable. Shoe interior length is another measurement again and should only be used when the manufacturer explicitly supplies it.
Nike’s men’s, women’s, and kids’ charts use related but distinct scales. On the men’s chart, US 10 is UK 9, EU 44, CM/JP 28, and Foot Length 27.1 cm. Read regional labels as a lookup on that exact row, not with an addition formula.
For a unisex release or a cross-scale comparison, use the scale stated by the product listing and locate its matching row in Nike’s current table. A conversion relationship can help identify a row, but it is not a final fit decision.
Width availability and fit notes vary by model and region. If your measured length fits but the forefoot is compressed, check whether that exact listing offers another width or a fit note. Changing to a longer size can change heel hold and toe room; it is not a general replacement for a width option.
Try shoes indoors according to the seller’s return policy. Check that toes lie flat, the heel is held during walking, and the upper does not cause forefoot pressure. If a result is unclear, choose only from the current official chart and the seller’s exchange terms rather than relying on a rule from another model.
Use Nike’s children’s table for a children’s item rather than converting from an adult row. Measure the child’s longer foot and compare it with the Foot Length column in that table. Follow only the allowance or fit information supplied for that product; this guide does not apply one universal growth allowance.
This is a demonstration, not a product recommendation: a person measures 27.0 cm on the longer foot. On Nike’s men’s footwear chart, they first find the Foot Length value nearest their measurement, then read that row’s US, UK, EU, and CM/JP labels. They check the product page for its own fit and width information before choosing.

Common sizing questions about Nike Footwear answered.
Nike does not publish one fit rule for every shoe or apparel item. Read the current product listing and the relevant Nike size chart; a label from another Nike model is only a starting point.
Do not use a fixed addition. Read the US and EU values on the same row of Nike's current chart for the relevant men's, women's, kids', or product-specific scale. For example, Nike's men's footwear chart lists US 10 with EU 44, but that row does not make a universal conversion formula.
Nike publishes separate tables for different footwear audiences and for apparel. Use the table named for the item; do not assume a cross-scale relationship applies to every release.
Use Nike's current kids' footwear chart and measure the child's longer foot. Kids' labels, CM/JP labels, and foot-length values should be read from the same official table.

Adidas Ultraboost and NMD models tend to run half a size small due to the Primeknit upper. Size up half a size if between sizes.
New Balance D width is standard for men, B width for women. If you have wide feet, look for 2E (men) or D (women) width options.
