Shoes protect a person's foot (lower leg) from direct exposure to dampness, cold, heat and impacts on hard objects. Shoes are made from a lot of parts. Part of these parts, consisting of soft and thin materials, forms a blank designed to protect the slow surface of the foot. The other part, consisting of stiffer and thicker materials, forms the so-called bottom of the shoe, which serves to protect the running (supporting) surface of the foot.
