Product Description
A modern interpretation of a timeless essential. This updated cap toe Oxford is built on our new ORION last, featuring a softly chiseled silhouette, a roomier forefoot, and a secure, supportive heel—engineered for balanced proportions and all-day wear.
Crafted from Expresso Antique Calf, the uppers offer a rich, hand-finished depth of color with a naturally soft, supple feel. Inside, a full sheepskin lining enhances comfort, delivering a noticeably smoother, more luxurious fit from first wear.
Underfoot, the shoe is fitted with closed-channel single leather soles for a clean, refined finish. The Flex Goodyear welt construction, combined with vegetable-tanned leather insoles, provides the durability of traditional shoemaking while allowing for increased flexibility and enhanced comfort.
A versatile staple that bridges formal and everyday wear—designed with precision, built for longevity.

Orion Last
The ORION last is defined by its softly chiseled silhouette, offering a refined yet contemporary profile suitable for both casual and dress wear. It features a generous forefoot that provides ample space and comfort, while the elegantly sculpted heel delivers a secure, supportive fit that promotes stability throughout the day.
Designed with all-day wear in mind, the ORION last combines structured elegance with functional comfort, making it an excellent choice for those who value both style and ease.
Fit Note: The ORION last fits slightly larger for a comfortable fit. We recommend choosing half a size down from your HIRO last size for an optimal fit.
Note: All Meermin Shoes are UK Sized. General rule is to go 1 full size down from your US size. Orion Last Measurements:

Common Fit Questions
Can I use my sneaker's size as a reference?
Goodyear Welted shoes & sneakers are made & fit quite differently. Sneaker fit is quite forgiving, whereas in a Goodyear Welted pair of shoes you'd like to have a close and adjusted feel in order to have the best and most comfortable fit.
Said that, better to compare with another pair of Goodyear Welted or dress shoes you have or have tried before.
What do you recommend if I am in between sizes?
If you're in between sizes, size up. Too tight shoes will end up resulting uncomfortable or not wearable.
Do your lasts fit all the same?
No they don't. Said that, most of our lasts are UK E width (medium/regular fit) and you most likely will be wearing the same size across many of them.
We recommend checking our Lasts page for a more detailed description of each of the lasts we currently have in production.
I wear a special size, can you produce a pair for me?
Currently, our collection is produced in sizes 6 to 12. If you are looking for a size outside this range, we recommend signing up for the notification box on any item you like, as our team reviews this regularly to launch small productions of special sizes based on demand.
Unfortunately, we are not able to accommodate custom-made or individual special orders.
I wear orthotics—Can I remove the insoles?
The answer is no, but there are a few exceptions. The leather insole is a structural part of our shoes/boots, is where the Welt & uppers are stitched through the welting process, and so it cannot be removed.
Said that, there is one exception, which is our Ultraflex System construction, which aside from the structural leather insole also comes with an additional memory foam insole on top of it. This memory foam insole can be removed easily.
