150 manufacturing steps to make the perfect shoe – shoemaking at Sioux

Shoemaking

There are lots of steps involved in making a shoe. From developing the model in the first instance, to the stamping, sewing and putting the finishing touches to the shoe at the very end.

Up until the middle of the 19th century, every shoe was individually made to measure by shoemakers. Nowadays, specialised departments at our manufacturing site in Lousada, Portugal, ensure each individual step is executed perfectly.

Every shoe is made of two main components, the upper (the shaft) and the base (the sole). A high-quality shoe must go through a large number of manufacturing steps until the end product is created. The Grashopper alone, for example, consists of 30 individual components and around 150 manufacturing steps. Other models vary, depending on the  style in question.

As soon as each department is finished with their assigned task, the shoe is passed on to the next manufacturing stage.

However, even the best manufacturing process is redundant if the materials being processed are of low quality. This is why we rely on high-quality leather, manufactured in European tanneries, which boast a sustainable environmental management system.


DEVELOPING
MODELS

Even before the material or the colour of a shoe is chosen, the initial concepts for the design and the lasts must be developed. The model development department is responsible for all of these steps.

STAMPING DEPARTMENT

The stamping department cuts or stamps the leather to create individual components needed for the shoe upper (shaft). These parts are either cut out by hand or using a laser cutter (this usually takes place during the preparatory stages and prototype manufacture) or are stamped using a punching knife (in batch production).

ASSEMBLY DEPARTMENT

The assembly department is the key component of shoemaking, as it is here that the shaft (shoe upper) and the sole are assembled into the finished product.

FINISH

As the name implies, the finishing department is the final stage of the entire footwear manufacturing process. It is the final stage before creating the end product – it all comes down to the finishing. This is the stage where the final look of the shoe is created, and where it gets its final touches. The high-quality fats and creams are applied here, giving the leather depth, protection and radiance.

SHOE LAST

Lasts are moulds that are modelled on the foot, and every shoe is constructed around these lasts.

THE SEWING DEPARTMENT

The sewing department receives the (cut-out) individual components of the the upper shoe from the stamping department. This is done manually using a sewing machine.

MADE IN PORTUGAL

The typical Sioux shoe is created in Portugal with exceptional precision and attention to detail. Qualities such as longevity, optimal quality and traditional craftsmanship as well as unbeatable comfort are of utmost importance to us.
