Every time your foot comes in contact with the ground, you compress that midsole area. It responds by absorbing the blow and returning energy to you as you begin the next stride. This process is repeated thousands of times during a run. As you can imagine, the midsole becomes fatigued over the course of a couple miles and then needs time to rebound in between runs to return to its original, bouncy state.
After a few hundred miles, however, the midsole breaks down to the point of no return. Little aches and pains begin to arise. If that's the case, take them with you when you go to get fitted for your next pair. Keep Reading. Buying new running shoes is a big decision for runners.

The cushioning of traditional midsole materials degrade -in part- due to the slow release of air particles from the foam as your repeated foot-strikes compress them. Over time, the cushioning loses its resilience and gets flat and unresponsive.
As discussed, shoe companies have typically used a foam blend known as EVA Ethylene-vinyl acetate , or some variation of that material. EVA has proven to be a sufficient shock absorbing material for running shoes, being forgiving enough on impact but still having enough substance to help spring your weight forward on toe-off. However, some footwear brands have recently come out with new shoe technologies to help mitigate or delay this breakdown process. This material consists of thermoplastic polyurethane pellets fused together to create the Boost midsole.
Other brands such as Brooks, New Balance, Nike and Saucony have all come out with their own proprietary take on the best midsole cushioning materials. Each has its unique pros and cons for the discerning consumer. These can be of notable importance depending upon where you live, how you live, how you run and how you store your shoes. In colder temperatures, where there is less moisture in the air, your shoe actually firms up under-foot, creating a slightly stiffer shoe sole and ride on the run.
On the contrary, temperatures above the norm anywhere above 80 degrees may cause the cushioning elements of your shoe to soften up, again affecting both the ride and the feel underfoot. Residents of the Northeast face this challenge because outdoor temps can swing by more than degrees within the same calendar year!
