What are vulcanized shoes

Vulcanized shoes are sports and leisure shoes made by joining the "vulcanization method" with the sole and upper in the way of sulfur addition

(in order to strengthen the elasticity and hardness, the rubber is treated with sulfur). Vulcanized shoes add sulfur to the rubber on the sole to increase the elasticity and hardness of shoe rubber, which is vulcanized, not necessarily canvas shoes. Vulcanization was first invented by puma in 1960. Mainly: cow leather, canvas, PU (artificial leather), microfiber, denim, twill, etc. Except professional basketball shoes, others are made by vulcanization process, so vulcanization is only a process word. Vulcanized shoes are named after the manufacturing process: the vulcanization method in which the sole and vamp are connected by adding sulfur (put the shoes into a high-temperature vulcanizing cylinder for steaming for a period of time in the process of making shoes), and then take them out to make shoes. Canvas shoes stand out from vulcanized shoes and become fashionable shoes that go beyond the concept of vulcanized shoes. Canvas shoes carry more cultural and fashion content.
