Frequently Asked Questions

What EU size is US men's 9?

US men's 9 converts to EU 42–42.5 depending on the brand's last. If the seller offers only whole EU sizes, 42 is the standard pick; size-up to 43 for brands known to run small or for thick athletic socks.

Should I round EU sizes up or down for sneakers?

Up. Athletic shoes need about a thumb's width of space in front of the longest toe, and feet swell during exercise. A slightly roomy sneaker works with lacing and insoles; a tight one causes black toenails on runs.

Do wide widths change the EU size I should order?

Often, yes — many European brands don't offer US-style width options (D, EE, 4E), so wide-footed buyers compensate by going up half an EU size. If the brand does offer widths, keep your converted length size and change only the width.

Why is my EU size different in dress shoes than in sneakers?

Dress shoes are built on slimmer, more tapered lasts and are designed to fit closer than athletic shoes. Many men wear a half to full EU size larger in sneakers than in oxfords — both fits are correct for their purpose.
