The component parts of a shoe are four: the bottom (fund), external upper, inner lining of the upper and lining and insole (or foot). The fund is the part that goes to impact with the ground on which we walk and is usually rubber, leather or plastic. The external upper is instead the part of the shoe around the foot and is the real shoe shape and own. The internal coating (or lining of the shoe), is the material that covers the inside of the shoe and is in direct contact with the foot. Finally, the insole is planar or rather that part of the shoe which rests directly on the foot
The label on the shoes, or pictogram, contains the signs of the shoe materials. These can be leather, coated leather, textile or technical materials
The internal shape of the arch of the shoe is designed to provide a comfortable support that affects the entire sole of the foot or some specific parts indicated for optimal performance. Altogether, walking will be more pleasant and less tiring.
LIGHT AND COMFORTABLE
The shoe is lighter in overall average. A careful study in the manufacture of the materials allows for performance in everyday use less tiring and more comfortable.
