I bought this item approximately 6 months to a year ago for work and wanted to wait to write a review until I really knew how I felt about these shoes. Up to now I DEFINITELY feel a difference of better strength in my legs. & Ladies, this product for sure makes your butt and thigh muscles come through! They're super comfy, tough, and very nice-looking still. If you have a sit-down job, I suggest walking more often in your free time and/or around the house, it feels great!
