Investigation on the amount of shock absorbed by a sport shoe and the relationship of the different types of insole used in a shoe
What household materials can be used as in insole?
This report is about the different household material that can be used as a insole temporarily in our shoes before one can get a hold of a proper insole. It mainly talks about how a common object such as cardboard can be transformed into a insole, and how it stacks up against the insole of a sport shoe. The aim of this experiment is to find out if household items have the shock absorbing qualities the can be used as a temporary insole.
In order to ensure that the experiment is as accurate as possible, we will be cutting 4 different materials with the same thickness into the shape of an insole. After that, a heavy round object, in this case a pendulum, will be dropped from a fixed height of 40 cm from above the insole and dropped. Using the height bounced as a proxy to the amount of shock absorbed, the individual readings from the set-ups will be comapared to that of the sport shoe insole. The aim of this experiment is to find out if household items have the shock absorbing qualities the can be used as a temporary insole.
"Shock is absorbed through a process called damping—the dispersion or disruption of the energy caused by shock’s impact forces—absorbs the energy from shock by decreasing the amplitude (strength) of the shock energy’s wave or by changing the wave’s frequency. Absorption reduces or eliminates the adverse effects, injury, or damage to an object or individual caused by shock."

After research, we have results as evidence to prove that the insole made of felt is the closest to the shock absorbing qualities of the shoe insole.
This experiment can be applied to real life. As the insoles protects our feet by absorbing shock, when a shoe comes without a insole, one's feet may get injured before they can go out to get an insole. But, knowing which material comes closest to the shock absorbing qualities of an insole, one will not need to get one as the can make one on their own.
