Product Description

One of our most popular boot, now built on the all-new ROD last. With a fit that closely mirrors our trusted HOK last, this Chelsea boot is crafted for both comfort and versatility. Made using the finest boxcalf, this boot is meticulously hand-blocked on the last and features a one-piece wholecut pattern for a sleek and refined look. The key to its flexibility? The combination of our revolutionary Ultraflex System Construction and the Lightweight Cleated sole.

The Ultraflex System is a breakthrough in Goodyear Welt craftsmanship — a newly developed approach that blends superior quality, timeless style, and unmatched comfort. By combining advanced materials and innovative techniques, these Chelsea boots set a new standard in comfort for welted footwear.

Goodyear welted on the ROD last, these boots offer an exceptional fit with the added benefits of the Ultraflex System. The soft, supple underside of the French boxcalf leather ensures all-day comfort, while our lightweight cleated rubber sole provides excellent grip and durability without adding bulk. It's the perfect balance of performance and elegance — making these boots a game-changer in your wardrobe.

Rod Last

The ROD last features a casual round toe shape and a truly acommodating fit. As its sister HOK last, the ROD is a voluminous last, featuring a wide ball tread, providing superior comfort to the wearer. It is one of our most forgiving & comfortable lasts within our range. Providing excellent support while retaining a snug heel control so that the foot remains in place avoiding any slippage or sliding-forward to within the boot.

The ROD last is exclusive to the Ultraflex System range.

The Ultraflex System is our newest take on the Goodyear Welt construction — A whole new system developed from scratch where Quality & Style meet real Comfort. This system is a combination of materials & technique making these shoes, the most comfortable Welted dress shoe in the market. We've maintained the lines & look of our HOK last, but adjusted to be able to accommodate the double insole system during production, without affecting the overall fit.

The most popular styles on the ROD last are our Service, Jumper & Wholecut Chelsea Boots.

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.
