Firstly the logs are sawn up into planks then an important process starts, the drying of the wood. For newly sawn wood the drying process can take five weeks. The moisture content is reduced to around 11% to ensure stability of shape after machining. The planks are then cut up to different lengths according to the size of the bottom then milled to form the unique Troentorp instep which is the base of the anatomic sole, recommended by so many, that no other clog producer has. Adhesive is then put onto both the wood and the sole before they are pressed together. The bottoms are now put through a fine milling, then the nailing groove, the decorative stripe on the heel. Lastly the instep is polished and the outside of the bottom is varnished. LEATHER UPPERS
The leather hides are first inspected before we click out the uppers. Each model and size has its own die to give the best possible fit for the clogs. After clicking, the upper are stitched and have straps and buckles attached. LASTING
The uppers are soaked before the uppers are stretched onto the last. This way the clogs get a good shape already during production and not on the wearer’s foot. You can read more about the lasting in the “wet lasting” below.
Why do we stretch the leather over the last?
Unlike most other producers of wooden clogs, at Troentorp we stretch the leather uppers over the last before nailing the clogs. The leather must be treated as a living material and when lasting the shoes one must be careful since the level of stretch in the upper will depend both on the skin that is being used, and where in the skin the upper has been punched out. This is a very important stage in the production since it will ensure the clogs get a good fit and retain their shape.
What does wet lasting actually mean?
We soak the leather uppers in order to make them stretchable for the lasting. The leather should be stretchable without being spongy such that the fibers can slide smoothly. This is an essential property when the uppers are stretched onto the last. This way the clogs get a good shape already during production and not on the wearer’s foot.
How are the uppers held in place over the last?
If you look closely, you can see some small holes on the wooden bottoms. This is because the uppers have been stretched over the last and fastened with staples before the nailing process. These staples are then removed after the lasts are taken out from the clogs.
Does one last fit all feet?
To get as good a fit as possible we offer all our clogs in different types of lasts depending on if you have a wide or narrow foot. Many models also come with a padded instep for extra support.
The clogs are nailed with real nails rather than staples. This production stage is the most physically demanding. After the clogs have been nailed, the surplus leather is cut away. The clogs are then checked before entering a drying room. Once dry the clogs are put to cool down and then we remove the lasts.
