lisäkumi

Lisäkumi is a Finnish term that translates to "additional rubber" or "extra rubber" in English. It most commonly refers to a layer of rubber applied to the sole of a shoe. This additional layer is typically added to improve durability, provide extra grip, or offer additional cushioning.

In the context of shoe repair, lisäkumi is often applied to worn-out areas of the sole, such as the heel or the ball of the foot, to extend the lifespan of the shoe. Cobblers or shoe repair specialists will select a suitable type of rubber, cut it to the required shape, and then adhere it to the existing sole using strong adhesives. This process is a cost-effective alternative to replacing the entire sole or purchasing new footwear.

Beyond shoe repair, the concept of lisäkumi can extend to other applications where rubber is used for protection or enhancement. For instance, it might refer to extra rubber pads added to industrial equipment to absorb vibration or prevent wear. In some sporting goods, additional rubber elements might be incorporated to improve performance, such as in the soles of athletic shoes for better traction on various surfaces. The specific purpose of the lisäkumi dictates the type of rubber used and the method of application.
