These shoes are in great condition. The insole shoes a little wear but that is primarily due to removing a sticker from the inside of the shoe. The most visually distinctive feature of any On shoe are the hollow little ‘clouds’ or pods that run the length of the sole, adding cushioning and dispersing pressure, but also because they move laterally as well as vertically, they propel you forward and transition quickly. This unique feel to the On running shoes is apparent from the first time you put them on. There is a central channel in the middle of the On shoes which allows the individual cloud components to move separately, providing a natural range of motion and best responding to the individual runner’s gait. The CloudTec® sole in all On shoes is made from ‘Zero-Gravity’ foam, a signature EVA compound that is superlight, flexible and responsive.
