Adidas has launched the PureBOOST X running shoe for women. Built over three years, the shoe is very flexible with the upper part of the shoe completely separated from the outsole. The mesh upper, movable arch construction and innovative lacing system ensure the shoe is a perfect fit, while the flexible outsole allows the foot to move naturally. The adidas PureBOOST X model is already presented in brand stores and on the official website of the brand. The collection also includes two PureBOOST X by Stella McCartney models.
