Running is a very good way to stay active, it's easy, and all you need is a pair of shoes. The type of shoe you wear all depends on your athletic capability, the distance you are running and for what speed. Companies are constantly battling to build the best running shoe. And, in the end, the shoe you get does matter because they can be better or worse for the type of running you are doing. This then implies that the shoes effect the sport because they are of different quality.

Shoes have a very big carbon footprint. More than 25,000,000,000 shoes are manufactured every single year, and they harm the environment when they are made. The rubber in the bottom of the shoe is extremely harmful to the environment. The gases that are released spill into the air, intoxicating it. This adds to the pollution and danger against humans. Also, because shoes where out, due to the forces applied on them, users must replace them every 1-3 years depending on the user. This not only increases the demand for more shoes to be made but also creats waste for the environment.

How Running Shoes Affect a Runner's Performance

# data[].attributes.body
Runers put their shoes through a lot of stress. They put their weight on it, they pound it to the ground, they slide it against the floor and even twist it. In order for an athlete to meet his top performance, the shoe must be able not only to withstand these forces, but also prevent stress put on the runners foot by these forces.

There has been a huge change in running

shoes over time. When a runner is

running, there is a lot of impact on the

balls of her/his feet. When running a long

distance, the whole time is spent by

slamming your foot down under all your

pressure. Therefore, shoes have

had to have more cushioning to prevent

repetitive stress injuries. Yet too much cushioning

and the runner is weighed down by the shoes.

The perfect shoe has a perfect medium in

between amount of cushioning and weight

of cushioning. Old running-specific shoes did

not have these features, they were designed

for track running. So, to grip the track well,

there were spikes at the bottom of the shoe.

These spikes would not go through the shoe

into the poor runner's foot, but there was

no padding above it in the sole. So if the

runner was running for a long distance or

sprinting, she/he would get foot pains

because of the constant pounding of

there feet in the hard wooden sole and the

spikes beneath it. Ouch. Now, without the

developing pain over the run, an athlete can

run a mile in shoes like the 840v2 and not

have foot pain. This means in a long race,

a runner can increase in speed at

the finish without the horrible bruises in

their foot slowing them down.
