The super sleek Reebok Easytone Reenew is a training sneaker that is stylish, comfortable and helps you tone your body more efficiently. Built-in balance pods create instability and are engineered to tone three key areas of your legs: your hamstrings, gluteus maximus, and calves. Plus, they also have a synthetic mesh upper for breathability, a TPU heel clip for stability, and a molded PU sockliner.
