When it comes to the shape of the sole, the first thing that deserves attention is its structure: because there is no such thing as a sole, it is usually composed of several layers. The outer layer, which can be said to be the surface that touches the ground, is the so-called outsole. However, inside is the deck (brand) sole. This layer touches the feet.
If necessary, additional layers can be added between these soles. It is usually insoles, bumps and midsoles. For example, you can also use insoles to get more warmth, improve the foot climate or solve winter orthopedic problems. Many individual soles take different forms of this interaction:
heel:
One-piece heel, that is, how much the heel area is higher than the forefoot depends on the corresponding model.
Non-slip sole:
Half sole thin sole, to be installed later, made of lightly molded rubber.
Half sole:
The sole just above the sole of the foot is the so-called sole joint.
Wedge sole:
The sole gains a similar height in the heel area as the heel sole, but has a straight transition-that is, there is no real "heel".
Long bottom:
The classic sole extends from the heel to the toe.
Platform soles:
An unusually thick but consistent sole, that is, no raised heel area.
Contour sole:
The rubber sole has a clear contour and is suitable for difficult surfaces.
Bottom of the shell:
The edge of the sole pulls up slightly on the side similar to the outer shell-providing better protection.
In addition, depending on the shape, the types of shoes and soles are also different. For example, golf bottom or ridge bottom, to name just two examples.
The inner workings of the soles are also very different, because nowadays the soles usually contain the most modern technology. For example, these include GORE-TEX or so-called "beads", which can improve breathability, which are small balls in the sole to provide better cushioning. The sole never consists of two material surfaces glued together. However, the materials are relevant.
