Question

What is shock attenuation? What type of midsole mediates shock the best? Why doesn’t a soft midsole mediate shock the best? (3 pts)

Answer 1

Shock attenuation is the process of absorbing the impact energy which is generated due to foot and ground collision while running.

It reduces the shock wave amplitude that travels from feet to head.

Midsole is designed in a way to absorb the shock and provide the cushioning effect.

The firmer the midsole, the stiffer and heavier it will make the shoe and provides better shock absorption

It is sandwiched between upper and outsole.

soft midsoles are not good because-

• they wear faster. even though they have good shock absorption property.
• soft midsoles are lighter and hence do not provide stability while running.
• they are flexible and so not suitable for running. running requires firmer midsoles
