There are many kinds of heels, which can be generally divided into three categories: flat heel, middle heel and high heel, and have different shapes, such as rolled heel, pressed heel and inclined heel. The size and thickness of heels are thin high heels, thick high heels, horseshoe heels and semi-circular heels. The shape of heel can't be the same, it changes with the development of market economy and the change of clothing trend. If you must shape, it is difficult to adapt to the ever-changing shoes.

The biggest difference between the heel and the sole is that the sole is used as a separate part in shoes, and the heel needs to be used in conjunction with the sole. Generally, both men and women leather shoes use heels, and the sole height below the heel is the heel. The heel of men's leather shoes is generally about 2CM, while the heel of women's leather shoes can be as high as 10CM.
The heel is mainly made of rubber, and some heels are made of leather/hardwood. In women's leather shoes, the heel is often wrapped with leather, that is, a layer of leather with the same color and material as the fabric is wrapped at the heel to match the upper. The technical term is called fabric wrapping.
