Yes — ASICS generally runs true to size, especially in performance footwear and training apparel, with a fit designed for comfort, stability, and consistency rather than trend-driven silhouettes.
From my experience working with sportswear pattern grading, fit testing, and OEM manufacturing, ASICS is one of the more reliable brands when it comes to consistent sizing across seasons.
People often ask “Does ASICS run true to size?” because:
ASICS is frequently compared with brands like Nike or Adidas, which can feel tighter or more style-driven.
Official brand reference:

In most cases, yes.
ASICS designs both footwear and apparel to align closely with:
That means:
ASICS prioritizes fit reliability, not fashion-tight sizing.
From a production standpoint, ASICS follows a conservative, athlete-first fit approach.
This is very different from trend-led brands that intentionally alter fit each season.
Result:
ASICS sizing feels predictable — which athletes value.
| Product Type | Fit Accuracy | Notes |
|---|---|---|
| Running shoes | True to size | Some models offer wide options |
| Training shoes | True to size | Stable, athletic fit |
| T-shirts & tops | True to size | Slightly relaxed performance fit |
| Shorts & bottoms | True to size | Comfort-focused, not tight |
| Compression items | Slightly snug | Designed for performance support |
Key takeaway:
If you prefer a very tight or fashion-fit look, ASICS may feel more relaxed.
| Brand | Sizing Tendency | Fit Style |
|---|---|---|
| ASICS | True to size | Comfort & performance |
| Nike | Runs slightly small | Compression & speed |
| Adidas | Mostly true to size | Sport-lifestyle mix |
| Gymshark | Often runs tight | Aesthetic-driven |
ASICS is one of the least risky brands when ordering your normal size.
