Product Description
Meet the most comfortable cap toe Oxford Meermin has ever made — a modern evolution in both materials and construction. Crafted from exclusive Silkcalf leather sourced from the Netherlands, the uppers are exceptionally soft yet refined. Inside, a full sheepskin leather lining enhances the luxurious feel and softness.
This updated design features our brand-new Diamond soles — ultra-flexible, shock-absorbing latex rubber outsoles that deliver unbeatable cushioning with every step. Coupled with our Flex Goodyear Welt construction and vegetable-tanned leather insoles, this shoe offers the durability of traditional craftsmanship with the comfort of modern innovation.
It’s all built on the new ORION last: a softly chiseled silhouette with a generous forefoot and refined, supportive heel for all-day wear. The shoes come with elastic laces for easy on-and-off convenience, plus a spare pair of classic laces if you prefer a traditional look.
This is more than just a new cap toe — it’s a revolutionary combination of elegance and engineered comfort, setting a new benchmark in the Goodyear welted footwear space.

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?
Sure! Most of our ready to wear production goes from size 6UK to 12UK, but if you happen to wear a smaller or larger size, we can definitely help & specially make any pair from our collection for you. Please do contact our CX Team, we'll be delighted to assist you.
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.
