The midsole of my running shoes helps absorb shock when I run.
Midsole → It is formed from "mid-" (meaning middle) and "sole" (from Old French *sole*, meaning the bottom part of a shoe). The word "midsole" refers to the middle layer of cushioning in a shoe, situated between the insole and the outsole.
Think of the 'middle' ('mid-') part of a shoe's 'bottom' ('sole') — that's what midsole means.
