Guidi sizing and which boots run small

Guidi's own site marks 15 of its 55 shoe and boot pages Fits one size smaller, and 35 Fits true to size. Asking if the whole brand runs small misses the point because each cut follows its own pattern.

You cannot take your standard sneaker number across every rack and expect the same fit. Pull on the 310 front zip boot in black with straight raw denim. That 310 runs true to size, but owning it does not mean you take the same size in a 788Z.

The rule is the model number, not the zipper. The small cuts are the 788Z, 788ZI, 788V, 789, and 796ZI, where Guidi cuts close for a sleek silhouette. Back zip pairs like the 9086 fit true to size, but the 788Z at €1,365 on Guidi's own site demands one size up.

The back zip boots that run small

On Guidi's own site, style 788Z prints the explicit note: Fits one size smaller. The boot uses Goodyear welt construction, explained in how shoes are built, with 100% horse full grain leather and a leather sole.

The same one size smaller note appears on 15 models on Guidi's own site. Those pairs include the 796ZI back zip boot with a metal heel at €1,595, the 788ZI mid boot at €1,660, and the 788V at €1,320. The 789 high boot at €1,350 also carries it, where Guidi describes a snug fit for a sleek silhouette.

The front zip boots that fit true to size

The 310 front zip army boot at €1,240 and the PL2 Palombaro front zip boot at €1,455 both print Fits true to size. Back zip models like the 9086 at €1,335 and the Back Zip Low Boots at €1,300 also print Fits true to size. If you want to compare European sizing to your sneakers, check the designer shoe size guide.

Guidi also lists its 992X classic derby at €855 as true to size. Different cuts under similar names do not share the same pattern. On within, WDLT117 notes that the 992 lace up derby mule at $1,275 fits one size smaller, advising a true 43 to take 44.

What the official size table leaves out

Guidi's size guide page on guidi.it is a conversion table without measurements. It lists Europe 34 to 42 against France 35 to 43, UK 1 to 9, and USA 4 to 12. The table prints no foot length, no centimetres, and no insole length.

The chart stops at Europe 42 even though unisex boots sell up to size 47. Guidi notes each piece is handcrafted in Italy using artisanal processes that allow the leather to evolve and develop its own character over time. Guidi prints no stretch figure on any page, so buy the size that fits the day you try it.

The rule is the model number, not the zip.

Common questions

Do Guidi boots run small?

Guidi boots run small only on specific models like the 788Z, 788ZI, 788V, 789, and 796ZI, while 35 of 55 styles on Guidi's own site fit true to size. The fit depends on the model number rather than the zipper, because back zip pairs like the 9086 and Back Zip Low Boots fit true to size. Front zip models like the 310 and PL2 also fit true to size.

What size Guidi 788Z should I get?

Take one full size up from your standard European shoe size for the Guidi 788Z. Guidi marks style 788Z as fits one size smaller on its product page because that specific model is cut close for a sleek silhouette. If you wear an EU 37 in true to size boots, buy an EU 38 in the 788Z.

Do Guidi boots stretch?

Guidi prints no stretch figure anywhere and says only that the leather is made to evolve and develop its own character over time. No product page gives a stretch measurement, so buy the size that fits the day you try it.
