Shoe Fitting Tips
- Measure both feet - use the larger measurement
- Measure feet in the afternoon when they\'re slightly swollen
- Leave about 1cm (thumb width) space between longest toe and shoe front
- Consider the type of socks you\'ll wear with the shoes
- Walk around to ensure comfort - heel shouldn\'t slip
- For running shoes, go 0.5-1 size larger than casual shoes
How it works
A shoe size converter translates sizes between US, UK, EU, and centimetre systems. Each system numbers the same foot length differently, so conversion maps your foot length (or one system's size) onto another's scale.
Size relationships
EU ≈ US (men) + 33 UK ≈ US (men) − 0.5 Best anchor: foot length in cm
- foot length
- heel-to-toe in cm — the most reliable anchor
Worked example
- US men's size 9
- EU ≈ 9 + 33 = 42
- UK ≈ 9 − 0.5 = 8.5
US 9 ≈ UK 8.5 ≈ EU 42.
Good to know
- Men's and women's scales differ — US women's is typically ~1.5 sizes higher than men's for the same length.
- Brands vary, so measure your foot in cm and use that as the anchor.
- Try shoes on late in the day when feet are slightly larger.
