I had to change my five star review to a one star on March 31, 2011, three months after the purchase in December, 2010.

I bought the Ryka Women's Reform Athletic Toning Shoe shoes for my wife and she has been wearing them off and on for around three months now.

After some walking in them she has complained that her back aches. The design of shoes seems to work against the natural curve and arch of her feet and ends up causing stress after walking and wearing them for a while. So, in her case, toning no, pain yes.

She did like the size and color of the shoe, and the pair did fit well. But after more than a couple of weeks wearing them, neither she, nor I, could see that they had toned anything, But, they did cause her pain. She tried wearing the pair a few more times, but now they just lay in the corner of the closet, unused. I wouldn't buy her another pair because there isn't any benefit.
