The injection molded outsole and rubber outsole of leather shoes are different in process, which can be roughly summarized as the following three differences:

1, the difference in weight. Because of the production process and the choice of materials, the injection molded outsole of leather shoes compared to the rubber outsole is much lighter, but not from this point to judge the good and bad of the two.

2, different wear resistance. Because of the difference in materials, rubber abrasion resistance is very good, so it is not only better wear resistance, and the service life will be longer, compared to the injection molded outsole wear resistance is slightly worse, so the manufactured shoes are not suitable for abrasion-resistant sports.

3, the production cost is different. The production process of injection molded outsole is more complicated, and the manufacturing process is also more difficult, so its cost will be very high, which is the way few people will choose to use injection molded outsole now.

Different rubbers also have influence on different footwear:

1, abrasion-resistant rubber. Abrasion-resistant rubber is very good in abrasion resistance and toughness, so it is very durable, and this rubber material is usually used on the outsole of tennis shoes.

2, environmental rubber. Also known as recycled material rubber, this rubber outsole contains up to 10% recycled rubber, the main purpose is for environmental protection.

3, air rubber. Rubber contains air, there is a certain shock absorption function, but not very wear-resistant, not very widely used.

4, sticky rubber. Viscous rubber is characterized by better flexibility, and very non-slip, generally used in indoor sports shoes.

5, hard rubber. Hard rubber is the most comprehensive rubber material in the outsole rubber material, tough, non-slip and very wear-resistant, the use of nature is also very wide. Multi-functional shoes and basketball shoes are mostly made of this kind of rubber to do the outsole.

6, carbonized rubber. In the ordinary rubber material added carbon elements, making the rubber more tough and wear-resistant, running shoes are mostly used in this rubber, and in the back of the running shoes sole part of the palm will be left BRS letter marking, in order to indicate that the outsole used carbon rubber.
