After introducing the sneaker world to its Zig technology, Reebok received a sort of boost. Then, it implemented the technology to its running shoe and it literally took off. For this spring/summer season, the Reebok Zig Sonic comes in a shark-colored upper with kiwi and malibu blue accents by way of the Reebok branding and soles. They’re available for purchase now for $100 retail in adult sizes. Have any of you given these a tryout yet?
