Frequently Asked Questions
What is a US men's size 10 in EU and UK shoe sizes?
US men’s size 10 = EU 43 = UK 9.5 = JP 28 cm (foot length). The EU size is derived from foot length in centimeters: EU size ≈ foot_length_cm × 1.5 + 1.5 (Paris points). Note that EU sizes are often listed as 43 or 43.5 depending on brand. Always measure your foot for the most accurate fit, as brand sizing can vary by up to half a size.
What is the difference between US men's and US women's shoe sizes?
US women’s sizes run about 1.5 sizes larger than men’s for the same foot length. So a women’s size 9 = men’s 7.5 in foot length. A women’s size 8 has a foot length of about 25 cm, while a men’s size 8 is about 26 cm. EU and UK sizes are the same scale but use different starting points for men and women — always specify gender when converting.
How do I measure my foot length at home to find the right shoe size?
Stand barefoot on paper and trace around your foot. Measure from the heel to the tip of the longest toe (usually the big toe, but some people have a longer second toe). Measure in cm or inches. Measure both feet and use the larger measurement. Measure in the afternoon when feet are at their largest. Add 0.5–1 cm (0.2–0.4 in) to your measurement for comfortable shoe fit.
Do shoe sizes differ between brands and shoe types?
Yes, significantly. A Nike size 10 may fit differently than an Adidas size 10 or a formal dress shoe size 10. Running shoes often run half a size large for toe box room. Steel-toed boots may run narrow. Whenever ordering online from a new brand, check the brand’s specific size chart based on foot length in cm or inches rather than relying solely on the size number.
What is a toddler shoe size and how does it differ from children's sizes?
Toddler sizes (typically 1T–10T or 0–10 in ‘T’ notation) cover roughly ages 1–3 years with foot lengths from 9.5 cm to 16.5 cm. Children’s/Little Kids’ sizes (1–3) pick up where toddler ends. Big Kids’ sizes (3.5–7 or 3.5–6Y) overlap with small adult sizes. US children’s size 1 = EU 32 approximately. A child’s foot grows about 1 cm every 3 months in early years.
