Product Description
Our Heritage Shell Cordovan Jumper Boot is a high-quality, premium boot that is designed to stand the test of time. The upper is made from Meermin's exclusive Heritage Shell Cordovan leather, which is a rare and luxurious material known for its durability, lustrous shine, and beautiful aging properties.
The boot features a classic jumper style with a high shaft that extends just above the ankle, giving it a timeless and sophisticated look. The leather is hand-stitched with a double row of waxed thread for added strength and durability, while the interior is lined with soft leather for comfort. The leather insole molds to the shape of the foot over time, providing a customized fit that ensures maximum comfort.
The outsole is made from JR leather, which is a top-quality leather that provides excellent traction and durability. The sole is welted, meaning it is stitched to the upper for added strength and easy replacement. The combination of the JR sole and the Shell Cordovan upper makes for a boot that is not only durable but also provides excellent support and stability.

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.
