Description

Manufacturing method of waterproof socks

The present invention relates to a pair of socks, in particular to a method for manufacturing waterproof socks.

In recent years, socks have gradually replaced shoes made of plastic leather uppers and become the mainstream. Compared with traditional shoes, socks can provide better wearing comfort and will not cause discomfort to the user's feet due to large-area pressure and friction. However, the technical threshold and cost of socks are relatively high, so some businesses have developed shoes made of socks as the main component. However, in addition to being thin and not warm, the socks are also not waterproof or breathable, causing the following problems. When going out on rainy days, the socks cannot prevent rainwater from seeping into the wearer's feet, which makes the wearer's feet feel uncomfortable due to dampness and is prone to some skin diseases. In addition, socks without soles generally do not have any function of protecting the soles of the feet, and are prone to foot pain due to direct impact on the feet. The lack of support can easily cause foot fatigue when standing for a long time. If there are sharp protruding foreign objects on the ground, the feet will be injured due to lack of protection.
