Saucony Sizing & Fit Guide UK
Saucony is one of the few major running brands that offers Regular, Wide, and Extra Wide fittings across its range. That makes it the go-to choice for runners who struggle with standard-width shoes from On Running, Nike, or Salomon. As authorised UK stockists, we stock Saucony performance and lifestyle shoes and fit them daily. This guide covers sizing, width options, model-by-model fit advice, and how Saucony compares to other brands.
Do Saucony Run True to Size?
Yes — Saucony shoes run true to size in standard (Regular) width. Whether you're buying a Triumph 23 for long-distance cushioning, a Guide 19 for stability support, or an Endorphin Speed 5 for race day, your normal UK shoe size will be correct.
Saucony has been making running shoes since 1898 (pronounced "SOCK-uh-knee"), and their sizing is well-established and consistent across the range. The FORMFIT system used in modern Saucony shoes creates an underfoot cradle that shapes to your individual foot, which means even at true-to-size the shoe adapts to you.
Quick Sizing Summary
- Neutral running (Triumph 23, Ride 19, Kinvara 16) — true to size
- Stability running (Guide 19, Hurricane 25, Omni 22) — true to size
- Race/speed (Endorphin Speed 5, Endorphin Pro 5) — true to size; snugger performance fit
- Trail running (Peregrine 16, Xodus Ultra 4) — true to size
- Lifestyle/Originals (ProGrid Triumph 4, Jazz Original) — true to size; some retro models run slightly small
- Wide/Extra Wide variants — same length as Regular, just wider across the forefoot and midfoot
The only models where we occasionally see sizing questions are the Saucony Originals lifestyle range (Jazz, Shadow, ProGrid reissues). Some retro models can feel slightly snug compared to the modern performance range, so if you're between sizes in lifestyle models, go up a half size.

Width Doesn't Change Length
If you're buying Saucony in Wide or Extra Wide, choose the same UK size you would in Regular width. The Wide and Extra Wide options add room across the forefoot and midfoot without changing the shoe length.
Saucony Width Options: Regular, Wide, Extra Wide
This is Saucony's biggest advantage over competitors like On Running and Salomon, which only offer standard width. Saucony manufactures three width options across many of their core models:
Regular (Standard)
The default width. Equivalent to a D width in men's and B width in women's. Suits the majority of runners and is the width you'll receive unless you specifically order Wide or Extra Wide.
Wide
Wider across the forefoot and midfoot. Equivalent to a 2E width in men's and D width in women's. Ideal for runners who find standard shoes tight across the ball of the foot or who have bunions.
Extra Wide
The widest option. Equivalent to a 4E width in men's and 2E width in women's. Designed for runners who need maximum room in the toe box and midfoot. Also suitable for orthotics users who need extra volume.
How to Choose
If standard-width shoes from any brand feel tight across the forefoot, start with Wide. If you've been sized as EE or wider, or use custom orthotics, try Extra Wide. Same UK size in all widths.
Why Width Matters for Running
- Feet swell during runs — a shoe that feels fine standing can feel tight at mile 5
- A too-narrow shoe causes blisters, black toenails, and bunion aggravation
- Sizing up for width creates heel slippage and instability — choosing the correct width at your true size is always better
- Saucony is one of only three major running brands (alongside New Balance and Brooks) offering multiple widths in the UK

Saucony vs Nike vs ASICS Size Comparison
Saucony sizing is consistent with other major running brands. Here's how they compare:
| Brand | Compared to Saucony | Width Options | Notes |
|---|---|---|---|
| Nike | Same size | Standard only | Nike can run narrow in some models; Saucony Wide is a good alternative |
| ASICS | Same size | Some Wide options | ASICS sizing is very consistent; direct match |
| On Running | Same size | Standard only | If On feels too narrow, try Saucony Wide |
| Salomon | Same size | Standard only | Salomon sensiFIT can feel tighter; Saucony is roomier |
| New Balance | Same size | Wide & Extra Wide | Both brands offer multiple widths; NB has even more width options |
| Brooks | Same size | Wide & Extra Wide | Brooks and Saucony have similar width offerings |
| adidas | Same size | Standard only | adidas sizing is consistent; direct match |
Switching from Nike or On Running?
If you currently wear Nike or On Running and find them tight across the forefoot, Saucony in Wide at the same UK size is usually the perfect solution. You get the same length with more room where you need it, without sizing up and losing heel hold.
Saucony Sizing Tips
From fitting Saucony in-store every day, here's what we recommend:
- Measure both feet. Most people have one foot slightly larger than the other. Always size to the larger foot.
- Width first, then length. If a Regular width shoe feels tight across the ball of your foot, switch to Wide at the same UK size. Do not go up a full size to compensate.
- Running socks matter. Bring the socks you actually run in. Cushioned running socks can make a half-size difference compared to thin everyday socks.
- Afternoon is best. Feet swell during the day. Fitting after lunch gives you the most accurate size for running.
- FORMFIT does the work. Saucony's underfoot cradle shapes to your foot over the first few wears. The shoe should feel good immediately but will feel even better after 10-15 miles.
- Originals vs Performance. If you're buying Saucony Originals (Jazz, Shadow, ProGrid reissues) for casual wear, be aware these can run slightly small. Go up a half size if between sizes.
Orthotics Users
- Remove the existing insole before inserting your orthotics
- The Echelon 10 has a FOUNDATION PLATFORM specifically designed for orthotics compatibility
- Choose Wide or Extra Wide to give your orthotics enough room
- Try in-store with your orthotics to get the right fit

Frequently Asked Questions
Do Saucony shoes run true to size UK?
Yes. Saucony shoes run true to size across the entire performance range including Triumph, Ride, Guide, Hurricane, Endorphin, and Peregrine models. The only exception is some Saucony Originals lifestyle models (Jazz, Shadow, ProGrid reissues) which can run slightly small — go up a half size if between sizes.
Does Saucony come in wide fit UK?
Yes. Saucony offers Wide and Extra Wide options across many core models including the Triumph 23, Guide 19, Hurricane 25, Echelon 10, Ride 19, and Peregrine 16. Choose the same UK size as Regular — Wide and Extra Wide add room across the forefoot and midfoot without changing length.
How does Saucony sizing compare to Nike?
Saucony and Nike use the same UK sizing, so buy the same size in both. The key difference is width: Nike is standard width only, while Saucony offers Regular, Wide, and Extra Wide in many models. If you find Nike shoes tight across the forefoot, try Saucony Wide at the same UK size.
What is the widest Saucony shoe?
The Saucony Echelon 10 is the widest-fitting shoe in the range, available in Regular, Wide, and Extra Wide. It features a FOUNDATION PLATFORM designed to accommodate custom orthotics and has the most generous toe box across the Saucony lineup. The Triumph 23, Guide 19, and Hurricane 25 also come in Wide and Extra Wide.
Are Saucony good for overpronation?
Yes. Saucony has a dedicated stability range: the Guide 19 (daily stability with CenterPath technology), Hurricane 25 (max cushion stability), and Omni 22 (daily stability with HOLLOW-TECH guidance). All three correct overpronation without feeling heavy or rigid. See our Saucony Pronation Guide for detailed advice.
