Guidi: A Collector's Guide to the Leather, Boots and Sizing

Few names in dark avant-garde footwear carry the authority Guidi does, and the reason is unusual: the label sells shoes, but it began, and still operates, as a tannery. The leather in a pair of Guidi boots is prepared in the same Tuscan town where the company was founded in 1896. For collectors, that vertical control is the whole story. It explains the depth of the colour, the way the hide loosens and darkens with wear, and why so many other designers in this corner of fashion send their patterns to Pescia to be made up. This guide covers where Guidi comes from, how the leather is tanned and dyed, how the boots are built, how the sizing works, and how to look after a pair.

The house: a Tuscan tannery since 1896

Guidi's roots are in Pescia, a small town in the heart of Tuscany where leather tanning goes back to the Middle Ages. A tanners' guild existed there by the second half of the fourteenth century, and by 1427 records list shoemakers, furriers and a saddler working within it. That craft tradition is the ground the company grew out of.

The tannery itself was founded in 1896, when Guido Guidi, Giovanni Rosellini and Gino Ulivo partnered with a joint stock of 75,000 Italian lire to establish the Conceria Guidi Rosellini in Pescia. When Giovanni Rosellini died on 23 August 1923, his share passed to the other partners and the company was renamed Successori di Guidi e Rosellini. It was enlarged again in 1934 with the purchase of an adjoining building. Through those changes the tannery stayed in the same family, and it is still managed by the Guidis today, currently led by Ruggero Guidi under the company GUIDI 1896 SRL.

For most of its history Guidi was a supplier rather than a consumer brand: a tannery that prepared distinctive leathers and bespoke treatments for designers around the world. The consumer line most collectors know, the luxury footwear and leather goods sold under the Guidi name, was introduced in 2004. That two-track identity, tannery first and label second, is why Guidi occupies a different place from an ordinary shoe brand. The same house tans the hide and builds the boot, and everything from raw skin to finished object happens in Pescia.

The leather: vegetable tanning and object dyeing

Guidi's signature is the leather, and specifically the way it is tanned and coloured. The tannery works by vegetable tanning without a varnish top coat. Rather than covering the hide with a sealing finish, the process is meant to bring out its natural grain, so the surface can show veins, scratches, tonal shifts and small irregularities. Guidi is explicit that these are not defects. They are the result of a finish designed to reveal the leather rather than hide it, and the same skin will keep changing colour and character with use as it ages with its owner.

The most recognisable material is full-grain horse leather, the hide used across the core boots. Retailers describe these boots as object dyed, meaning the colour is worked into the finished piece rather than sprayed on as a flat surface coat. Guidi's own care notes point to the same thing from the other direction: the natural, piece-dyeing methods can affect the oxidation of the metal hardware, so the tone of a zip or eyelet may vary slightly from one pair to the next. That is the trade-off collectors accept and often seek out. No two pairs are identical, and the finish reads as depth rather than uniformity.

Because the colour sits in the leather instead of on top of it, early wear can include some colour release, and the surface develops a patina quickly. This is the behaviour that separates Guidi from a conventional polished boot, and it is worth understanding before buying, because a Guidi that looks slightly uneven out of the box is doing exactly what it was made to do.

Construction: Goodyear welt, soles and lasts

Under the leather, Guidi's boots are built to last and to be repaired. The core models use Goodyear welt construction, where the upper and the welt are stitched to allow the sole to be replaced without rebuilding the shoe. On the signature back-zip ankle boot, the 788Z, that welt is paired with a stacked leather block heel and a leather sole, finished with logo-engraved antiqued silver-tone hardware. It is a fully leather-bottomed boot, dressy in profile despite its heft.

Guidi does not build every model the same way. Some boots swap the leather sole for a treaded Vibram rubber sole and a stacked rubber heel, which is the setup on models like the 796LVX, trading the dressier leather bottom for grip and weather resistance while keeping the Goodyear welt. Others, like the calf-high Palombaro front-zip boot (model PL2), keep the leather sole and Goodyear welt but sit on a taller, more structured shaft in 100 percent horse reverse leather. Many of these are effectively made to order: Guidi lists certain styles as custom made and shipped within roughly twelve weeks, which underlines that these are built individually rather than pulled from deep stock. For a closer look at how welts, soles and lasts read across the avant-garde category, our guide to reading the avant-garde boot sets Guidi alongside Rick Owens and Ann Demeulemeester.

The models: reading Guidi's numbering

Guidi identifies its shoes by number rather than by name, which can be daunting at first but becomes readable with a little familiarity. The 788Z is the reference point, an ankle-high horse-leather boot with a zip at the heel, and much of the range varies from that base. The 796LVX is the Vibram-soled sibling of the same ankle silhouette. The 9086 is a squared-toe boot, again with a heel zip and Goodyear welt, while models such as the VS01 move the zip to the vamp and add a pull-tab at the collar. The Palombaro (PL2) is a named, calf-high front-zip boot that sits above the ankle styles. The letters and digits generally flag the closure and sole rather than a season, so two similar numbers often mean two versions of one last with different hardware or bottoms. When you are shopping the archive market, the model number is the most reliable way to compare like with like.

Sizing and fit

Guidi uses Italian and European sizing, and its boots are typically sold in whole and half sizes across the IT range, with made-to-order styles offered in half-size increments. Fit, though, is not uniform across the line, and this is where buyers get caught out. Guidi's own product pages give a fit note per model rather than a single house rule. The current Palombaro (PL2), for example, is listed as fitting true to size, whereas other lasts in the range have historically been described as running slightly small, so sizing advice that holds for one boot will not always hold for the next. The practical rule is to read the fit note on the specific model you want, and if you are buying secondhand where no note exists, to work from measured insole length rather than the labelled size. Guidi lasts also vary in width and volume between the ankle boots and the taller shafts, so a size that works in the 788Z is a starting point, not a guarantee, for the Palombaro.

If you are new to the archive market generally, our framework for authenticating archive designer fashion covers how to read construction, hardware and labelling before you commit to a pair, and Guidi's own Certilogo program is the house's route to verifying a piece.

Care: keeping the leather alive

Because the leather is vegetable tanned and unvarnished, Guidi asks for a specific, low-intervention care routine, and following it matters more than with a sealed boot. Wet shoes should be dried at room temperature, never near a direct heat source such as a radiator or the inside of a car in summer, because heat damages the natural tanning and shortens the life of the leather. During drying, Guidi recommends leaving paper towels inside and replacing them every three hours, then nourishing the leather with a neutral cream once dry. Storage is just as important: keep the boots away from strong light, high humidity and unventilated spaces, and never store them in a plastic bag, which traps moisture against the hide. For longer-term storage of leather and other archive pieces, our care guide to storing and preserving archive garments goes further.

Where Guidi sits, and how to buy it

Guidi's standing in this world is partly its own line and partly its role behind other labels. As a tannery it remains a trusted partner for designers who rely on it for distinctive leathers and bespoke treatments, which is why Guidi leather turns up in the collections of avant-garde houses well beyond its own shelves. That dual presence, a brand in its own right and a supplier to its peers, is a large part of why the leather carries the reputation it does. Our comparison of Guidi and A1923 looks at how two Italian leather houses approach the same material differently.

At ninesells⁹ we treat Guidi as a cornerstone of the leather side of the archive. Pieces move quickly and are often one of a kind, so we keep sold examples on the site as a price reference for collectors tracking the market. The Guidi 788Z black horse-leather back-zip boot in our archive is a good illustration of the reference model discussed above. You can browse the full Guidi collection and the wider men's archive to see what is currently available.

Frequently asked questions

Is Guidi made in Italy?

Yes. Guidi is made in Italy, with its tannery, production and headquarters all in Pescia, Tuscany, where the company was founded in 1896.

What leather does Guidi use?

The core boots are made from full-grain horse leather, vegetable tanned without a varnish finish so the natural grain, veins and tonal variation show through. Guidi treats these marks as features of the material rather than flaws.

What does object dyed mean on a Guidi boot?

Object dyed means the colour is worked into the finished piece rather than applied as a flat surface coat. Because the dye sits in the leather, the finish has depth, varies slightly from pair to pair, and can even influence how the metal hardware oxidises.

Does Guidi fit true to size?

It depends on the model. Guidi gives a fit note per style: the current Palombaro (PL2) is listed as true to size, while some other lasts have been described as running slightly small. Check the note for the specific model, and when buying secondhand, work from measured insole length.

How do I care for Guidi leather?

Dry wet boots at room temperature away from direct heat, replacing paper towels inside every three hours, then nourish with a neutral cream. Store away from strong light, humidity and heat, and never in a plastic bag.
