Materials For A Running Shoe

Nike Free Run Shoes

Do you know how a running shoes is made of ? this post tell you the answers

A Running Shoes is made up of three parts: the upper, the midsole and

the outsole.

1.

Upper: Holds the foot in place, protects the foot from rocks and

dirt, has synthetic leather for durability, mesh for breathability

and reflective material for safety.

2.

Midsole: The most important part of shoe. There are three

materials that make up the midsole:

EVA: Lightweight, foam-based cushioning.

Dual-Density EVA: When you double the density of something it gets

stronger, firmer and heavier (twice the mass in the same amount of

space).  The dual-density EVA is called a "medial post".  'Medial'

because it is on the inside of the shoe and 'post' because it has a

beginning and an end. The length of the post determines the amount

of control.

Polyurethane: Very durable cushioning. More durable/stable than EVA

and weighs more than EVA.

New forms of EVA or combinations of EVA and rubber midsoles are

being developed at increasingly faster rates. These new foams are

lighter and provide you with more durability. Look for brand name

foams like Mogo, Solyte, Acteeva and others.

Outsole: Has tread for traction, flex grooves for flexibility and

protects from dirt/rocks. The outsole is made of two materials:

Carbon Rubber: The most durable (same material as tires).

Blown Rubber: Lighter, more flexible and more cushioned, but not as

durable.
