Our craftsman select, cut, and harvest the alder trees used to make the wood soles of the clogs. At our factory saw mill, the logs are milled and cut into long strip planks, and then cut into smaller wood blocks. The blocks are shaped and sized in a wood lathe. The polyurethane outsole and the wood insole are bonded together. After several more steps of precision cutting and sanding, the product is ready to be nailed with the leather.
The leather hides are first inspected, and than the leather is 'clicked' into a upper. Each model and size has its own leather type to ensure the best possible shape for the clogs. After clicking, the uppers are stitched into specific designs, and various accessories are attached such as buckles and laces.
The clogs are hand-nailed with steel shank nails. This production stage is the most physically demanding and requires the most skill. After the clogs have been nailed, the excess leather is cut away.
Wet lasting is the process of soaking leather in water and then pre-stretching it to a proper shape. Wet-lasting is a rare technique used in shoemaking but we find it necessary to achieve a comfortable and properly fitting clog. We believe it is an essential step because it ensures the leather is properly shaped during production and not on the wearer's feet. In other words, your clogs will not lose their fit and get sloppy.
Here is our process at Troentorp:
Before the leather is nailed to the footbed, it is soaked in water and stretched over a last. The moisture in the leather allows it to properly shape itself and stretch to a higher capacity. The leather must be soaked for a precise amount of time. If it is too wet, it becomes spongy and unusable. If it is too dry, the fibers cannot slide smoothly and stretch.
Once the leather is properly soaked and moistened, it stretched over a last. This is where the leather and the wood footbed come together. The last is temporally nailed to the center of the insole and the leather is temporally stapled to the sides of the sole. This secures everything together while the leather stretches and dries for 24 hours.
When the leather is ready, the shaped leather is nailed to the footbed and the staples and last are removed. This completes the production process. The result is a properly formed clog. Also, you will notice a small nail hole on the center of your insole which is the result of the last nailing. You may even notice tiny staple marks on the sides of the wood sole. These are not defects. Think of these marks as signatures or the character of your hand-crafted clogs.
