Reebok has released the second wave of new colors for its next-generation running shoe, the ZPump Fusion, for the fall/winter season, starting in September. The ZPump Fusion features the brand's unique "The Pump Technology," which allows for a custom fit that integrates the foot and shoe to suit each individual's foot shape and characteristics. A total of 21 colors will be available this fall/winter season. Nine colors will be available from September to November. The September model features a resin upper for improved stability. In October, a highly designed ZPump Fusion featuring graphic designs by digital art pioneer Andy Gilmore will be released.
