Parts of a shoe

It's been really interesting reading about the different parts of a shoe. The definitions are making it reasonably simple to write descriptions for my each of my posters. I've been trying to relate object which associate with older people to sports shoes.

Sole

The bottom of a shoe is called the sole.

Insole

The insole is the interior bottom of a shoe, which sits directly beneath the foot. Many shoes have removable and replaceable insoles, and extra insoles are often added for comfort (to control the shape, moisture, or smell of the shoe) or health reasons (to help deal with defects in the natural shape of the foot or positioning of the foot during standing or walking).

Outsole

The outsole is the layer in direct contact with the ground. Dress shoes have leather outsoles; casual or work-oriented shoes have outsoles made of naturalrubber or a synthetic imitation. The outsole may comprise a single piece, or may comprise separate pieces of different materials. Often the heel of the sole is rubber for durability and traction, while the front is leather for style. Specialized shoes will often have modifications on this design: athletic cleats have spikes embedded in the outsole to grip the ground; many kinds of dancing shoes have much softer or harder soles.

Midsole

The layer in between the outsole and the insole that is typically there for shock absorption. Some types of shoes, like running shoes, have another material for shock absorption, usually beneath the heel where one puts the most pressure down. Different companies use different materials for the midsoles of their shoes. Some shoes may not have a midsole at all.

Heel

The bottom rear part of a shoe is the heel. Its function is to support the heel of the foot. They are often made of the same material as the sole of the shoe. This part can be high for fashion or to make the person look taller, or flat for a more practical use.

Vamp/Upper

Any shoe has an upper part that helps hold the shoe onto the foot. In the simplest cases, such as sandals or flip-flops, this may be nothing more than a few straps for holding the sole in place. Closed footwear, such as boots, sneakers and most men's shoes, will have a more complex upper. This part is often decorated or is made in a certain style to look attractive.

Lateral/Medial

The outside part of the shoe is referred to as the lateral and the inside facing part of the shoe is the medial. This can be in reference to either the outsole or the vamp.
