This is the 2nd pair of shape-ups that I've gotten. I got this shoe because of the obvious: it's suppose to tone up your lower body and help with your posture. I do notice the workout in my legs and bottom everyday that I wear them. I have chronic lower back problems and wearing these takes a HUGE amount of pressure off my lower back. I love them! They are very cute and stylish but slightly less comfy than their "sleek fitness walking shoe."
