The world of rubber soles

First, let's look at the origin of rubber. Rubber is a natural material that comes from the sap of various plant species, such as the Indian rubber tree, dandelion, taraxacum, parthenium, funtumia and landolphia. Brazil was once the largest producer of natural rubber, but today there are many countries that produce rubber worldwide, including the Philippines.

The juice is extracted from the plants, filtered and diluted with water and acid. It is then rolled into thin slices and dried. This process produces the raw rubber that is used for the production of various products, including rubber soles.

Rubber vs. synthetic and EVA

While rubber soles have many advantages, there are also some disadvantages compared to synthetic and EVA soles. Rubber soles are generally heavier than their synthetic and EVA counterparts, which can be a disadvantage in certain sports or activities where weight is an important factor.
