The boot is a shoe that, in addition to the foot, covers the ankle and part of the leg. It can have a heel, which in turn can be distinguished from the rest of the sole or constructed in a single piece. Similarly, some boots close with laces or zippers, others do not have a closure. Today boots (often made of leather) that are high below (and above) the knee are very common in western women's clothing. In addition to aesthetics, the boot is used for protection from water and mud, and in this case it is often made of rubber and does not have a closure.
