Saucony Shoe Sizing Guide: Do They Run Small?
Saucony fits true to size — your usual US size is usually the first size to check. The brand leans slightly narrow through the midfoot on most models, which is the one nuance to know: if your foot is wide, check for the 2E width on the Ride and Triumph lines before sizing up in length. Otherwise, Saucony is among the most predictable running brands for fit.
Across our data Saucony true to size: 15% of wearers report it runs small, 72% true to size and 13% large.
Saucony sizing philosophy
Saucony was founded in 1898 in Pennsylvania and has been a performance running brand for most of its history. Its lasts are calibrated for a standard US runner's foot — neither as narrow as On or Saucony's own race lasts, nor as generous as Brooks or New Balance — which is why "true to size" is the honest answer for most buyers. The fit reference model is a neutral foot with moderate arch and D width.
The brand's range spans neutral trainers (Ride, Kinvara, Triumph) and stability shoes (Guide, Tempus), and both categories sit on similarly calibrated lasts at the brand-level. Where Saucony differs internally is in the upper: the mesh on the Endorphin Speed is snugger and more race-oriented than the knit on the Triumph, even though the lasts are similar in length.
How Saucony models differ
There is no single "Saucony size" — different lines are graded on different lasts. Here is how the key models compare:
- Ride (daily neutral trainer)
- The accessible entry point: true to size, slightly narrow through the midfoot. The reference model for "what does Saucony sizing feel like."
- Kinvara (lightweight)
- A race-influenced flat with a snug, performance feel. True to size in length, but the narrow last means wide feet often go half a size up.
- Triumph (max cushion)
- The most voluminous Saucony — slightly more forgiving than the Ride. True to size; the 2E wide is available and genuinely useful for wide feet.
Practical sizing advice
If you normally wear US 9, start by checking Saucony in US 9 — the brand fits consistently true to size across its range.
If your feet are wide
Saucony offers a 2E wide grade on the Ride and Triumph lines — the right solution for wide feet. The standard D in Saucony runs slightly narrow compared to Brooks or New Balance at the same size, so choosing the 2E is more important with Saucony than with some other brands.
