1. Coin: The so-called coin refers to Putian shoes made of ordinary materials. You can use any cheap material. This is just a trademark. Although it can be worn and sold cheaply, the cost is there and the quality can be imagined.

2. Super A: Compared with currency, the materials selected by Super A are much better in quality and durable. Super A requires strict workmanship, but improper handling of details will save some materials.

3, true standard: true standard does not mean genuine, just better than Super A, in terms of quality and details, true standard can be called the leader in Putian shoes. There is no fixed standard for the real standard, so you need to be careful when buying the real standard!

4. Company level: The company level is naturally several grades better than the real standard. As the name implies, the company level refers to the same level as the company's goods. Company-level Putian shoes are made of the same material as the company, with reliable quality assurance and very fine workmanship, even better than the products of some companies.

5, top version/poison version: good shoes need polishing. The top edition belongs to the top copy, with raw materials and original technology. Because it is the top grade, the workmanship is much more detailed than other grades.
