What is the tongue and what is the tongue?

<> tongue generally refers to the part between the underside of the lace and the top of the instep, because its shape is a bit like the tongue, so it is called the tongue, and the color of the material used in the tongue will generally match the main color of the upper or the color of the logo or the shoelace. The term tongue is generally used in sports shoes, because it involves the breathability of shoes, so the tongue material is mostly perforated mesh. For a comfortable fit during exercise, a thin layer of foam is often added between the front and back of the tongue.

In some shoes, the tongue is divided into upper tongue and lower tongue, and the part near the toe is called the lower tongue, and vice versa. Generally, there will be a brand logo on the front of the tongue, and the size mark of the shoe will be ironed on the reverse side of the tongue. For certain shoes, there will be a lace piercing at the upper tongue that is passed through the lace to secure the tongue.

Because the tongue material is on the sunny side, the yellowing resistance test and phenolic yellow test will be relatively focused on physical testing.
