Quick Answer

Most Nike products run slightly small, especially performance shoes and fitted training apparel.
Nike uses a performance-focused fit, meaning products are designed to feel secure and supportive rather than relaxed.

💬 OEM Insight:
Nike grading follows athletic proportions — narrower shoes, closer-to-body tops, and tapered fits.

1. Does Nike Run True to Size Overall?

Nike is close to true-to-size, but tends to run slightly small due to its athletic design philosophy.

General sizing summary:

Category	Fit Feel	Notes
Running shoes	Slightly small	Narrow toe box
Training shoes	True to small	Support-focused
Lifestyle shoes	True to size	Air Force 1 fits larger
Men’s apparel	True to fitted	Tapered cuts
Women’s apparel	Runs small	Especially leggings

💬 OEM Insight:
Nike’s patterns prioritize performance, which means less “extra ease” compared to casual brands.

2. Nike Sizing by Category: Shoes vs Apparel

Nike sizing varies depending on the product type.
Here’s a breakdown from both consumer feedback and OEM manufacturing perspective.

✔ Nike Shoes

Tend to be narrow
Heel and midfoot are snug for stability
Running lines are the most fitted
Air Max and lifestyle shoes run truer

✔ Nike Apparel

Training leggings: run small
Running tops: true to fitted
Hoodies: true to slightly big
Compression gear: intentionally tight

💬 OEM Insight:
Nike reduces fabric ease to enhance performance — resulting in a tighter overall feel.

3. Why Nike Often Feels More Fitted

Nike’s sizing system is based on athlete movement, not casual wear.

Key reasons:

Performance needs compression and stability
Less extra material = better mobility
Narrower shoe designs improve running mechanics
Tops are tapered for aerodynamic feel
Leggings have higher spandex content for hold

This design philosophy makes Nike feel smaller than relaxed-fit brands like Adidas Originals or Puma lifestyle.

4. How to Choose the Right Size

Here is a simple guide for shoppers deciding whether to size up or stick with normal sizing.

✔ For Nike shoes

Wide feet → size up 0.5
Running shoes → size up 0.5
Lifestyle shoes → true to size
AF1 / Air Max 90 → sometimes size down

✔ For Nike apparel

Training leggings → size up
Compression gear → true to compression fit
Oversized hoodies → true to size
Running tops → true to fitted

Who should size up?

Beginners who prefer comfort
People between sizes
Anyone new to Nike’s performance fit

Who should stick to TTS?

Athletes
Runners
People who prefer a locked-in feel

5. What New Activewear Brands Can Learn

Nike’s sizing teaches new brands valuable lessons:

✔ Lesson 1: Decide your fit identity

Oversized brand? Compression brand? Hybrid?
Sizing must match brand purpose.

✔ Lesson 2: Consistency builds trust

Nike’s sizing rarely changes — customers rely on predictability.

✔ Lesson 3: Test across multiple body types

Better fit = fewer returns.
