Saucony Sizing UK: The Quick Answer

Do Saucony trainers fit true to size? There is no single answer that applies to every Saucony model. Your usual UK shoe size is a useful starting point, but the fit can change with the shoe’s shape, width and intended use. For the Saucony ProGrid Omni 9 sold by Forever Sourcing, our individual product listings recommend choosing half a UK size larger than your usual size because this model fits slightly small.

For example, if you normally wear UK 8 and are buying the ProGrid Omni 9, UK 8.5 is the size to consider first. This is a model-specific recommendation, not a rule for every Saucony trainer. Always review the size selector and product details before purchasing.

Do Saucony Trainers Fit True to Size?

Saucony makes different types of footwear, from performance running shoes to retro-inspired lifestyle trainers. Two pairs with the same UK size label may feel different around the toes or midfoot. That does not necessarily mean the size chart is wrong; last shape, materials, sock thickness and personal fit preference also affect how a shoe feels.

The safest approach is to use Saucony’s official size conversions as a reference, then follow fit advice for the exact model you want. Customers with wider feet or those between sizes should pay particular attention to toe room and upper pressure rather than relying on the size number alone.

Saucony UK Size Chart: UK, EU, US and CM

Below is a practical selection of conversions from Saucony’s official men’s footwear size chart. This is a reference chart, not a promise that every model will feel identical. The centimetre column follows Saucony’s published sizing convention.

Important: women’s sizing and unisex sizing are not interchangeable by label. For Saucony UK unisex styles that use the men’s scale, Saucony’s own conversion chart lists a women’s UK 6 as a unisex UK 5.5. Refer to the sizing system specified on the exact product page, and use the official Saucony size chart for full conversions.

How Does the Saucony ProGrid Omni 9 Fit?

The ProGrid Omni 9 is the most important model for Forever Sourcing shoppers because it is the main style in our Saucony collection. It has a technical mesh-and-overlay upper and a structured retro-running silhouette. On several product pages, we advise customers to go up half a size from their usual UK size because the model fits slightly small.

That recommendation appears on our ProGrid Omni 9 Silver Grey, ProGrid Omni 9 Black Silver and ProGrid Omni 9 White/Touch listings. Checking individual product guidance is particularly useful if you have never worn the Omni 9 before.

Should You Go Half a Size Up in Saucony?

Consider half a size up when the specific model’s product guidance recommends it, when you are between sizes, or when your toes feel crowded in your usual size. For the ProGrid Omni 9 on Forever Sourcing, the half-size-up recommendation is the clearest place to begin. Going up a full size without checking fit can leave too much movement at the heel, so avoid treating bigger as automatically better.

What If You Have Wide Feet?

If you have wider feet, pay attention to the forefoot as well as the overall length. A larger size might reduce pressure, but it may also make the shoe too long. Where a performance Saucony model is offered in a specific width fitting, check that option first. For lifestyle releases without a clearly marked width choice, compare the centimetre measurement and product guidance, and contact the retailer if you are uncertain.

How to Measure Your Feet Before Ordering Saucony Trainers

Measure your feet at home if you are between UK sizes or have not bought Saucony before. It is better to measure both feet than to assume your usual trainer size is universal.

1.       Place a sheet of paper on a hard floor against a wall, and stand with your heel against the wall.

2.       Keep your weight on the foot being measured and mark the end of your longest toe.

3.       Measure the heel-to-toe distance in centimetres. Repeat with the other foot and use the longer measurement.

4.       Compare your measurement with the correct Saucony chart, then check the fit recommendation for your chosen model.

5.       Make sure there is comfortable toe room without excessive heel slip. Try on shoes indoors while keeping them in returnable condition.

Saucony’s own fitting instructions also recommend measuring while standing naturally, rather than sitting, because your feet spread under weight.

Saucony Men’s, Women’s and Unisex Sizing Explained

One common source of confusion is assuming a unisex UK size equals the same women’s UK size. On Saucony’s UK unisex chart, the unisex size follows the men’s numbering. As an example, unisex UK 7 corresponds to men’s UK 7 and women’s UK 7.5 on that chart. This conversion is not the same thing as sizing up for fit: first identify the correct size system, then decide whether the particular shoe runs small.

Look for “unisex”, “men’s” or “women’s” in product information. If the Forever Sourcing listing shows only UK sizes without a clear sex-specific scale, seek clarification rather than assuming a conversion. Saucony sizing UK searches often come from exactly this uncertainty.

Choosing Your Size for Everyday Wear Versus Running

The intended use of a trainer matters. For casual wear, people often prefer a secure everyday fit with comfortable space at the toes. During longer runs, feet may swell and require additional room; Saucony notes on some performance-shoe pages that ordering up to a size above a regular shoe size may be appropriate. That performance recommendation should not be applied automatically to a lifestyle ProGrid Omni 9 purchase.

The Omni 9 now appeals to many buyers as a retro lifestyle style. To learn more about its background and design, read our Saucony ProGrid Omni 9 guide.

Does Colourway Affect Saucony Sizing?

A different colourway of the same model is not normally a reason by itself to change your size. The ProGrid Omni 9 Silver Grey, Black Silver and White/Touch all belong to the same model family, although manufacturing details and individual fit preferences can still vary. Check the specific product’s sizing note, not just its colour.

Once you know your size, you can compare styles in our best Saucony ProGrid Omni 9 colourways guide, or browse lighter options such as ProGrid Omni 9 White Grey.

What to Check Before Buying Saucony Trainers Online

6.       Confirm the exact model. A ProGrid Omni 9 recommendation is not necessarily right for another Saucony silhouette.

7.       Check whether the listing uses men’s, women’s or unisex sizes, especially if buying a unisex model.

8.       Read the product-specific sizing recommendation, and consider your foot width and whether you are between sizes.

9.       Use the collection filters to find your UK size, then confirm availability on the product page.

10.   Review the [Forever Sourcing returns policy](https://foreversourcing.co.uk/pages/shipping-returns) before ordering. Eligible items may be returned within 14 days of arrival, subject to the published conditions.

Frequently Asked Questions About Saucony Sizing

Are Saucony trainers true to size in the UK?

Many shoppers can start with their usual UK size, but fit depends on the model. Forever Sourcing recommends going half a size up for the ProGrid Omni 9, which our listings describe as slightly small.

Do Saucony ProGrid Omni 9 trainers run small?

According to Forever Sourcing’s current product descriptions, yes, the ProGrid Omni 9 fits slightly small. Consider half a size above your usual size, especially if you are between sizes.

Should I size up in Saucony if I have wide feet?

Possibly, but a longer shoe is not always a better fit for a wider foot. Look for width choices when offered and check for pressure across the forefoot. If unsure, ask about the specific model before buying.

Is Saucony UK sizing the same as Nike or ASICS?

Not necessarily in fit, even when the printed UK size looks the same. Different shoe shapes can alter how much room you feel. Use the Saucony chart and model-specific fit advice rather than assuming that a UK 8 will feel identical across brands.

How do Saucony unisex sizes compare with women’s UK sizes?

Saucony’s UK unisex chart runs on its men’s sizing scale. For example, unisex UK 6 corresponds to women’s UK 6.5 on that chart. Check which sizing convention a particular retailer is using before buying.
