并不是说要把鞋子穿坏穿破才算是寿命终结。报告结果就是连续受压以后的foam比休息以后的foam恢复的要差，失去弹性的速度加快了，从而鞋子寿命也缩短了（不是说鞋子本身坏的快）。
“Not wearing the same shoes two days in a row also means that the foam in the sole of the shoe will have an opportunity to decompress before you wear them again. You are applying a lot of force with each foot strike, and the rubber will get a tiny bit denser and take a little bit of time to go back to it’s normal state. If you never allow it to completely get back to it’s normal uncompressed state, then it’s normal state will begin to default to being a little compressed.”
"The midsole layer of a shoe provides the cushioning and stability. This area usually wears out before the outsole shows major signs of wear. When a midsole wears out the shoe looses functional stability. "
