Nike vs Adidas - women’s footwear size comparison

Trying to figure out if Adidas fits the same as Nike? We look at brand fit data like foot length and how snug or roomy the shoe is, so you can predict how Adidas will feel compared to what you already own from Nike.

This page is focused on women’s footwear. Different shoe brands can run longer, shorter, tighter, or looser even when the size label looks “the same.” Our converter helps you find the closest match before you buy.

Why Nike women’s footwear and Adidas women’s footwear don’t always match

Two brands can both call something “the same size” and still fit totally differently. Nike might feel a little longer in the toe, while Adidas might be snugger through the midfoot. Even a couple of millimeters can change how secure or loose a shoe feels.

Our tool compares real fit data, not just the printed size label. That means if Nike tends to run longer and Adidas runs shorter, we’ll tell you up front before you buy.

How to use this

  1. Pick the size you already wear in Nike.
  2. We’ll show you the closest recommended size in Adidas, plus how much longer/shorter or tighter/looser it may feel.
  3. You can expand the details to see measurements.
