Just earlier today we showed our readers a fresh new colorway of the Reebok Zig Sonic that recently dropped. The brand has chosen to feed off of the Zig technology's success and create the Reebok RealFlex, which celebrities Ali Larter and Josh Duhamel have agreed to help launch. The Reebok RealFlex is said to have "natural movement perfected," meaning it is made to feel as though you're walking on your bare feet. It is relatively light, at 9 oz. and comes with 76 independent sensors that help make movement and flexion feel natural. The release coincides with mid-April's Earth Day and will be made available for purchase from several retailers.
