Quick Answer
Adidas generally runs true to size, though some categories fit differently:
- Running shoes → slightly narrow
- Lifestyle sneakers → true to size
- Training apparel → fitted
- Originals apparel → relaxed
💬 OEM Insight:
Most fit differences come from last design, fabric stretch, and regional grading, not from quality issues.

1. How Adidas Sizing Usually Fits
Adidas focuses heavily on athletic performance, so many products have a structured, supportive fit.
General fit notes:
- Narrower shoes compared to Nike
- Training tops are fitted for movement
- Originals clothing fits looser
- Leggings offer medium compression
Why this matters
A product can be “true to size” yet still feel snug due to performance shaping.
2. Adidas vs Nike vs Puma Size Comparison
Fit Comparison Table
| Brand | General Fit | Notes |
|---|---|---|
| Adidas | true-to-size / slightly narrow | performance-focused |
| Nike | smaller / narrow | especially in running |
| Puma | true-to-size | lifestyle-friendly |
Interpretation
If Nike feels tight, Adidas may feel slightly more comfortable — but still not wide.
3. Why Adidas Fits Differ by Product Line
Adidas sizing changes depending on the athlete and use-case.
Fit differences by category
| Category | Fit Style | Reason |
|---|---|---|
| Running | snug & supportive | speed + stability |
| Training | balanced fit | full movement range |
| Originals | relaxed | streetwear audience |
| Soccer | narrow | precise foot control |
OEM Insight:
Fit is impacted by fabric elasticity, seam engineering, and movement requirements.
4. How to Choose the Right Adidas Size
If you prefer a snug performance fit
→ Choose your true Adidas size.
If you have wide feet
→ Go half a size up (especially running shoes).
If buying Originals apparel
→ Stick to your normal streetwear size.
Leggings
→ Size up for comfort.
→ Size down for compression.
For high-intensity training
→ True-to-size gives the best support.
5. OEM Insights for Brands Creating Better Fits
✔ Lesson 1: Don’t use one grading system for all categories
Adidas varies by sport — smaller brands should too.
✔ Lesson 2: Test on diverse body types
This increases global size consistency.
✔ Lesson 3: Use fabrics with predictable stretch
Unstable fabrics = inconsistent sizing.
