When it comes to footwear, few brands match the heritage and craftsmanship of Grenson. But no matter how well-made a pair of boots or shoes is, the wrong fit can ruin the experience.
Grenson sizing isn’t always as straightforward as you might expect. While they use standard UK sizing, their width fittings and lasts can make a big difference in how each style fits.
That’s why understanding the Grenson size chart is essential—it helps you navigate their unique sizing system with confidence.
In this guide, we’ll break down everything you need to know about Grenson sizing, from width options and last shapes to fit tips for narrow and wide feet.
Let’s start by looking at their official size charts and how it translates across different sizing systems.
Grenson Size Chart
Grenson uses standard British sizing, so if you’re familiar with UK shoe sizes, you’re already one step ahead. Simply go with the size you normally wear in similar styles. However, there are a few key points to keep in mind to ensure the best fit:
Narrow Feet? Consider Sizing Down: If your feet are on the narrower side, you might find that sizing down by half works better, especially in styles with a G fit (Grenson’s wider fitting). This helps eliminate excess room and ensures a snug, secure fit.
Wide Feet? Stick to Your Size: If you have wider feet, Grenson’s G-fit lasts are designed to give you the extra space you need. Just double-check the last details to confirm the fit.
Whether you’re shopping from the US, Europe, or elsewhere, the size charts will help you translate your local size to Grenson’s UK sizing.

Let’s take a closer look at how it applies to the Fred Country Boots…
Grenson Fred Country Boots: Fit & Sizing
Grenson’s Fred Country Boots use UK sizing, and they run about half a size large. That means if you’re used to US sizing, you’ll want to size down accordingly. UK shoe sizes are typically one full number down from US sizes, so if you measure as a US 8.5 D on a Brannock Device, your best fit in these boots would likely be a UK 7.5 in standard width.
Now, let’s talk about width—because UK brands don’t exactly make it easy. Grenson, like RM Williams, labels their standard width as a G width. Sounds straightforward, right?
Not really. Some UK brands call their regular width H, while others go with C—so there’s no universal standard. Just know that in Grenson’s case, G is their normal fit.

How Do They Fit?
The Fred boots give you a snug but comfortable fit. The last is fairly wide at the ball of the foot, but it narrows at the heel, locking your foot in place without feeling restrictive.
The rounded toe shape is another plus—your little toes aren’t cramped like in some sleek dress boots, but there’s also no extra room for wiggling. Instead, they feel anatomically well-proportioned, giving you a secure, natural fit that works well for all-day wear.
Now, let’s dive deeper into Grenson width system—because when it comes to UK width labels, things can get a little tricky.

Grenson Width Fittings Explained
When it comes to Grenson shoes, the fit is just as important as the style. Their width fittings—ranging from D to G—are designed to accommodate different foot shapes, but understanding which one works for you can make all the difference.
Let’s break it down…
‘D’ Fitting: The Standard for Women
The ‘D’ fitting is Grenson’s standard width for women, and it’s designed to fit most people true to size. However, the toe shape of each style can affect how roomy or snug the fit feels.
For example, the Clara has a wider, round toe, giving it a roomier feel—perfect if you prefer a bit more space up front. On the other hand, styles like Juno and Martha feature a more tapered, pointed toe, which can feel snugger. If you’re between sizes or have wider feet, you might want to size up in these styles.
‘E’ Fitting: Narrow and Snug
The ‘E’ fitting is primarily used in Grenson’s women’s sneaker range and a select few men’s styles. It’s a narrow fit, so it’s best suited for those with slender feet.
In loafers, the ‘E’ fit is considered standard because a snug fit is essential to prevent slipping. However, if your foot is average width or wider, this fit might feel too tight—even if you size up. For most people, it’s a better fit for sleek, minimalist styles rather than everyday comfort.
‘F’ Fitting: The Standard for Men
For men, the ‘F’ fitting is the go-to standard width. It’s designed to fit the majority of men comfortably, but if your feet are on the wider side, you might need to size up slightly.
This fitting strikes a balance between snug and roomy, making it versatile enough for both lace-ups and loafers. If you’re unsure where to start, ‘F’ is a safe bet for most men.
‘G’ Fitting: A Roomier Option
The ‘G’ fitting is slightly wider than the standard ‘F’ and is ideal for men who prefer a bit more room in their shoes. Many find this fit more comfortable, especially for all-day wear, as it allows for natural movement without feeling too tight.
Both ‘F’ and ‘G’ fittings work well for most men, but if you’re between widths or have wider feet, ‘G’ is the way to go. Remember, it’s always better to have a little extra room than to feel cramped.
What is a Last?
Think of the last as the blueprint for every pair of shoes. A last is the 3D form—often shaped like a foot—over which the shoe’s upper is stretched to create its final shape.
The shape of the last dictates everything from toe room and heel height to arch support and overall volume. That’s why some lasts feel like they were made just for your feet, while others might leave you wondering if you’re wearing the wrong size. For example, a last with a rounded toe will feel roomier, while one with a tapered toe might feel snugger.
Every shoe company has its own unique lasts, and they guard these like trade secrets. Why? Because the last is what sets a brand apart. It’s their “secret sauce” for fit and comfort. While materials, stitching, and soles matter, the last is the foundation that ensures a shoe performs its intended function—whether it’s hiking up a mountain in hiking boots, running a marathon, or simply looking sharp at the office.
Some brands stick with the same lasts for decades because, well, if it works, why change it? Once you find a last that fits you perfectly, you’ll likely stick with that brand for life.

The Story of Grenson
Grenson isn’t just a shoe brand—it’s a piece of British heritage. Founded in 1866 by William Green in Northamptonshire, England, Grenson was born in the heart of a region renowned for its centuries-old shoemaking tradition. What started as a small, family-run workshop quickly grew into a powerhouse of craftsmanship, producing high-quality, handcrafted shoes for men that were as durable as they were stylish.
Over the years, Grenson’s reputation for excellence earned it a loyal following, including some rather notable names. Winston Churchill and the former Prince of Wales, now King Charles III, have both been spotted in Grenson shoes.
But like many heritage brands, Grenson faced its share of challenges. After the Second World War, the rise of cheap imports and shifting consumer tastes led to a decline in its fortunes. By the early 2000s, the brand was struggling to stay relevant.
Enter Tim Little. In 2005, Little was brought on as CEO and later became the sole owner and creative director by 2010. He saw potential where others saw stagnation. Little stripped away the old-fashioned elements that no longer resonated with modern consumers and injected a fresh design culture into the brand. Under his leadership, Grenson underwent a renaissance, blending its classic English charm with contemporary style.
Today, Grenson is a thriving brand with a global presence, yet it remains deeply rooted in its Northamptonshire origins. The company’s boots and shoes are divided into three distinct categories, catering to a range of tastes and budgets:
- G0 and G1: These lines are Made in Northampton, with G1 representing the pinnacle of craftsmanship. The difference lies in the details—G1 features an open-channel Goodyear welted sole, where the stitching is visible, while G0 uses a closed-channel construction, hiding the stitches under a split lip in the sole. Both lines showcase the finest materials and meticulous finishing.
- G2: While manufactured in India, G2 footwear is designed and sourced in Northampton. The Indian factory employs traditional, handmade techniques, often involving more handwork than machinery, ensuring that every pair maintains Grenson’s high standards.

Grenson Sizing FAQs
Do Grensons Run True to Size?
It depends on the style and last. In general, Grenson shoes and boots do not always fit true to size—many styles run half a size large, so sizing down is often recommended.
- Men’s standard width (F fit) and slightly roomier G fit: Most men’s shoes fit true to size in these widths, but wider feet may prefer the G fit for extra space.
- Women’s standard width (D fit): Typically fits true to size, though toe shape can affect the overall feel. Pointed styles might feel snugger, while rounder-toe designs offer more room.
- Boots, like the Fred Country Boot: These tend to run half a size large, so if you’re between sizes or prefer a snug fit, consider going down half a size.
If you’re unsure, check the last used for a specific model, as different lasts can affect the fit.
What is the size F in Grenson?
In Grenson sizing, F fit is the standard width for men. It is designed to fit most average-width feet comfortably. If your feet are on the wider side, you might find an F fit slightly snug, in which case you may want to size up or opt for a G fit, which provides extra width.
For women, Grenson does not commonly use F fit—instead, their D fit is the standard width.
Do Grenson Nanettes fit true to size?
Grenson Nanette boots tend to run slightly large, so most people find that sizing down half a size provides a better fit. This is especially true if you prefer a snug fit or plan to wear them with thinner socks.
Overall, sith their variety of width fittings and lasts, some styles may run roomier or snugger than expected. By understanding the Grenson size charts, recognizing how different lasts affect fit, and considering your own foot shape, you can make avoid unnecessary returns.
