Shoe sizes vary by country! UK size 8 = US size 9 (men) / 10 (women) = EU size 42 = CM 26.5. India generally uses UK sizing. The easiest way to compare is by foot length in centimetres — measure your foot and convert to any system. Women's US sizes are typically 1.5 sizes larger than men's for the same foot.

❓ Frequently Asked Questions
Why do shoe sizes differ between countries?▼
Different countries developed their own sizing systems independently. US sizes use a different scale than UK (US men = UK + 1). EU uses Paris points (2/3 of a centimetre). Japan and Korea use centimetres. This creates confusion for international shoppers and is why knowing your foot length in cm is most universal.
How do I measure my foot for shoe size?▼
Stand on paper, trace around your foot, measure the longest distance heel to toe in cm. Add 1-1.5cm for comfort. Use this measurement to find your size in any system. Always measure both feet — most people have one foot slightly larger. Buy for the larger foot.
What is the difference between men's and women's shoe sizes?▼
Women's US sizes are typically 1.5 sizes larger than men's for the same physical foot size. A women's US 8 = men's US 6.5 in actual foot size. Women's EU and UK sizes also differ from men's. Our converter handles this automatically when you select gender.
What does 'wide fit' mean?▼
Width sizing is separate from length. Standard widths: B (narrow), D (standard), E/EE (wide), EEE (extra wide) in US/UK. EU uses narrow/normal/wide. Width varies significantly between brands — always check brand-specific sizing charts for width.
Should I size up or down if between sizes?▼
Always size up if between sizes. A shoe that is slightly long (with thin socks) is better than one that is too tight. Leather shoes stretch over time. Athletic shoes should have about 1cm of space between longest toe and shoe end. Tight shoes cause blisters, bunions, and foot problems.
