Would wearing extra socks make me faster? : Eco Answers

You may know that I am non stop on the
search for fun ideas on
Alternative Energy Sources. Today, I
ran into a very
informative piece of content that talks
about Eco Energy Sources from a different
perspective. Today’s fun article is titled Would wearing extra socks make me faster? .
Question by : Would wearing extra socks make me faster?
I trust physics on my life.

Here’s a small fact on my physic textbook:

“Running shoes as shock absorbers: Today, much of the focus of running shoe technology centers on the cushioned midsole that plays a key role as a shock absorber and performance enhancer. Each time a runner’s foot hits the ground, the ground exerts an equal and opposite force on the runner’s foot. This force can be nearly four times a runner’s weight, causing aches and pains, shin splints, and damage to knees and ankles over long distances. Cushioning is used in running shoes to decrease the force absorbed by the runner. As a runner’s foot hits the ground and come to a stop, its momentum changes. The change in momentum is Δp = FΔt.

A shoe’s cushioning system also affects energy consumption. The bones, muscles, ligaments, and tendons of the foot and leg are a natural cushioning system. But operating this system requires the body to use stored energy to contract muscles. So if a s shoe can be worn that assists a runner’s natural cushioning system, the runner does not expand much of his or her own stored energy. The energy the runner saved can be spent to run farther or faster. The cushioned midsole uses the law of conversation of energy to return as much of the energy to the runner as possible. The runner’s kinetic energy transformers to elastic potential energy, plus heat, when the runner’s foot hits the running surface. If the runner can reduce the amount of energy that is lost as heat, the runner’s elastic potential energy can be converted back to useful kinetic energy. Bouncy, springy, elastic materials that resist crushing over time commonly are used t o create the cushioned midsole. Opt ions now range from silicone gel pads to complex fluid-filled systems and even springs to give a runner extra energy efficiency.”

So would wearing extra sock reduce the amount of energy lost, which I can spend to run faster? (I get tired pretty easy.)

Answer by Lacey J
probably not because they would just squish your feet in your shoes not to mention make them hotter faster.

The power system has often been cited as the greatest and most complex machine ever built, yet it is predominantly a mechanical system. However, technologies and intelligent systems are now available which can significantly enhance the overall functionality of power distribution, and make it ready to meet the needs the 21st century. This book explains in detail how sensors, communications technologies, computational ability, control, and feedback mechanisms can be effectively combined to create
