Size Check: Your Go-To Guide for US, UK, and EU Shoe Size Conversions

Oct 7, 2025

Sneaker shopping is supposed to be fun — not stressful. But nothing kills the vibe faster than copping a fresh pair online and realizing they don’t fit when they land on your doorstep. Whether you’re grabbing the latest Jordan drop, locking in a classic adidas silhouette, or lacing up for the season in Nike, knowing how to navigate US, UK, and EU shoe sizes is key.

If you’ve ever wondered how to convert your size when switching brands or buying from a global release, you’re not alone. Sizing systems can be confusing — but we’ve got you. Consider this your easy guide to understanding the basics so you can shop with confidence and rock your kicks right out of the box.

Why Shoe Size Conversion Matters

Sneaker culture is global — and so is sizing. The US, UK, and EU each have their own systems, and brands use them differently across men’s, women’s, and kids’ lines. A men’s US 9 isn’t a UK 9, and your EU size might not line up the way you think. If you’re chasing a hyped release or switching brands, knowing how sizes compare helps you avoid surprises and keep your style locked in.

The Basics: US vs. UK vs. EU

Here’s a quick breakdown of how sizing systems stack up:

  • US sizes are the most common here in the States and what you’ll see first when shopping online.
  • UK sizes are typically one size down from US men’s and about two sizes down from US women’s.
  • EU sizes use a completely different scale (measured in Paris points) — they’re often seen as the most “universal” but don’t always translate to a perfect whole number.

A classic example:

  • A US Men’s 9 = UK 8 = EU 42.5
  • A US Women’s 8 = UK 6 = EU 39

Pro tip: Always double-check size info before you buy — even within the same brand, some models (especially performance shoes or collabs) can run slightly different.

Sizing Tips for Sneakerheads

Know Your Fit Game
Different styles fit differently. Retro Jordans, running shoes, and lifestyle silhouettes might all feel unique on foot. If you’re going after a snug performance fit, stay true to size. If you’re copping something more lifestyle-driven for daily wear, a half size up can give you extra comfort.

 

Don’t Sleep on Brand Differences
Nike and Jordan often run a little smaller, while adidas and New Balance can lean true to size or slightly roomier. If you’re switching brands, comparing the EU size is usually your safest bet since it stays more consistent.

 

Pay Attention to Unisex Pairs
Many hot drops today are unisex. When you see a men’s size listed, remember women’s sizing is typically 1.5 sizes up. For example, a men’s 7 = a women’s 8.5.
