Your questions answered

Our leathers come from tanneries with ancestral expertise located in France, Spain, and Italy.

Our partner tanners use recycled food waste in some of their production processes.

The K.Jacques tradition is based on a meticulous selection of leather.
Before starting to make our collections, we carry out a series of tests on leather samples (resistance to folds, friction, humidity, etc.).
This is an essential step in our process that improves the quality of our products.

Tanning is the process of transforming a hide into leather using tannins, a variety of natural substances (vegetable, mineral, or a combination of both).

Leather is an exquisite organic material that evolves over time and according to a variety of factors like sun exposure, humidity, temperature variations, usage, etc.

To prolong the life of your leather, you need to care for it regularly, using the right products.

Our timeless pull up leather is a full-grain leather (which retains its thickness). It benefits from a deep tanning treatment that’s rich in vegetable oil, making it strong and supple. The color will darken and acquire a patina over time.


Our smooth “Odeon” leather is also a full-grain leather. It has been tinted on the surface for a silky-smooth finish. This treatment helps the leather to stand the test of time.

You can see that some of our models are made with thin “Baguettes” straps and others with wider “Coupé” straps.

Our designers choose the finishing leather with your comfort in mind, they also consider the nature of the leather and any technical constraints or other restrictions this imposes.

There are several options for the finish and our advisers are happy to help you find the right one for you.

Our Metal or laminated leather is more supple than our Metyl leather. Both have a surface treatment to reveal that shiny, luminous appearance. Metyl leather has a crumpled textured effect.


Both of these materials are delicate and need to be properly cared for. Metallic leathers are generally more sensitive to friction and shocks.

We offer a variety of leathers, each with its own specific properties. So our sandals can be more, or less supple, depending on the material used.

As a general rule, we say that some leathers are supple from the first wear, whereas others will soften as they are worn:

— Our supple leathers are suede, metallic suede, printed suede, laminated suede (metallic), nubuck, etc.
— All other leathers soften with wear. Our timeless pull up leather will adapt to your foot shape more quickly than other leathers.

Patent leather retains a certain stiffness over time.

Our laces are up to 2 m long and therefore need to be cut from very long pieces of leather.
You have a choice of the following:

—Timeless pull up leather,

—Metallic leather (silver metal, gold metal, bronze metal, peach metal, and metyl champan),

—Smooth leather (black odeon).

The colorimetry of our timeless natural pull up leather can vary from one tanning bath to another, with more or less brown/yellowy-orange tones because of changes in the concentration of mineral and vegetable pigments from one tanning bath to another.

Please note: our timeless natural pull up leather acquires a patina and darkens very quickly when exposed to light.

Nubuck leather means the outer surface (grained side) has been finely sanded to produce a velvety feel.

It’s a supple leather that’s soft to the touch.
Suede means the inner surface of the hide (flesh side) has been sanded to achieve an ultra-soft, velvety feel.


Yes, this is part of our traditional manufacturing technique.

All the straps on K.Jacques flat sandals with linen thread stitching are fixed under the sole using nails.

The nails should not hurt you in any way as our crochet technique makes the tip of the nails disappear.

You can see them if you zoom in on the product photos.

Don’t like the nails? We have developed other manufacturing techniques that don’t use nails.
