Often times, when a person attempts to find the perfect shoe, he finds himself either staring at a wall full of endless sneakers that all seem to look alike, or he pages from link to link on the web, all the while unable to figure out what is what. At long last, once a shoe has been chosen, he feels his toe box to make sure he can wiggle, and he stands up to see if his heel slides too much. Yet rarely does a buyer think about the part of the shoe that is the most important: the midsole.
While it does not seem to do too much, being in the middle and all, the midsole performs several critical functions that allow for an injury-free run. First, the midsole absorbs almost three times the force of your body weight at impact, thus making your foot strike much less hurtful than it could be. Second, it provides you with a rebound effect, with the shoe pushing off the ground in response to the impact, thus helping to propel you forward into the next stride. Next, the midsole actually helps to provide additional stability if you suffer from over-pronation. And finally, it disallows your foot from feeling most sharp or blunt objects, such as rocks, shells, or sticks, you encounter while running. Overall, it plays a pretty major role in the success and enjoyment in running, so giving it some attention is a good idea.
Generally, the midsole represents the most durable part of the shoe, as the front and side portions will often wear sooner. Being thicker and more pronounced, the midsole has the cushioning and stability to weather the stress each mile puts on the shoe, thus it does not show its age as rapidly. Yet do not be fooled into believing it performs no great function by its tough exterior and steadfast resistance. It may not be the most exciting consideration, and it may not look too cool, but it will give you the correct production if you take the time to learn about what it can do. Best of luck!
