I love Skechers shape-ups, perfect arch and cushion support for my feet and legs. I never feel tired while wearing them. No, I did not purchase them for their "butt and leg toning". I buy for comfort.
Tone-Ups - Spindrift Clogs are a good and stylish runner up. These are not for walking around Disneyland or a full day mall shopping, but I have my shape-ups for that.
