BROOKS AURORA Brooks Aurora 23cm BROOKS' highly anticipated super-cushioned model. These shoes are designed to help you run longer and more easily. Equipped with "DNALOFTv3," a new material developed by BROOKS' innovation center, "BlueLineLab." You can experience the ultimate softness, like the moment you first touch the ground in zero gravity. The midsole is made of "DNA LOFTv3," a new material created by mixing liquid nitrogen gas with the soft and durable "DNALOFT" and subjecting it to supercritical foaming. The midsole structure allows the heel and toe to move independently of each other, enabling free movement. Size: 23cm No box. Used sparingly and in very good condition. The ultimate cushioning model!! Items will be shipped in simple packaging. Thank you for your understanding!
