The construction technique of the Goodyear welt shoe dates back to 1869, when Charles Goodyear Jr. invented the machine used for this process. This particular technique is generally considered the best in terms of comfort and durability as well as ease of repair. The Goodyear method is highly regarded in the high-end shoe market because it allows shoes to be:
relatively waterproof (the way the sole is connected to the welt prevents water from reaching the inside of the shoe),
extremely comfortable after several uses (thanks to its cork filling, which is known to create a mold of the foot providing an almost customized footbed), and
easily repairable in terms of replacing the sole, which gives the shoe a rather long life that can reach decades if the upper is properly cared for.


In the Blake construction: the sole, the insole and the upper are sewn together. The main specificity of this shoe construction is that the lining is wrapped around the insole and fixed between it and the sole. A single point connects all that is visible inside and outside.
The Blake process was invented by the American technician of the same name Lyman Reed Blake in 1858. In fact, in 1856 he became a partner in a footwear company and mechanized the company as much as possible and made shoes of a certain level.
Flexible and resistant footwear
High comfort


The construction of the bag involves sewing the upper to a piece of flexible lining to form a “sock” bag, normally we also use them for unstructured footwear, that is, with a light upper with little structure that makes the shoe very flexible and light to the foot.
The seam is then placed on the edge of the shoe, this avoids any discomfort due to annoying seams.


Strobel processing guarantees lightness and flexibility. The upper is joined to a lightweight insole forming a pouch which is then joined to the sole. The Strobel construction allows to contain the weight, very important for shoes that require great comfort.Specific for sneakers
