Bisgaard's soles are made of natural rubber, that comes from rubber trees that grow in the tropics. Natural rubber ensures a durable, soft and flexible sole that follow the feet's natural movement. The natural rubber is drained through a cut in the bark and looks like a white and milky mass. When the rubber is dry, it develops a natural, soft texture. The rubber is delivered to the factories in large quantities. After that, it is heated and divided into smaller pieces that fit the individual sizes and soles.
In the production of the sole, the raw natural rubber is placed in a mold that heats the rubber to be molded to size. Excess rubber is removed and collected for recycling. Nothing goes to waste.
After the sole is molded, it needs to cool down before it gets shipped to the factories. Once cooled, it is shipped to be sewn or glued to the shoe.
Here you see the end result; a sole of natural rubber, that makes bisgaard shoes soft and flexible to wear. The final process of the production is the quality control of the product. It ensures a final product of high quality and beautiful finishes.
