I didn't know they were "toner" shoes.  I wish I had read the reviews since there is not a description of this specific shoe here on amazon (I have since read on Crocs website that they are described as "Spherical outsole design.").  I was looking at the pictures for overall style of the top of the shoe to gauge comfort etc. It never occurred to me that the bottom of the shoes would not be flat! Even when you look at the picture of the bottom of the shoe its difficult to see how rounded the shape is. You are literally walking on a padded sphere at the top and heal of the shoe. when I got them, I thought of returning them, but thought I would get used to them. Well its been about 6 weeks and I'm still wobbly and tripping whenever I where them. I don't understand all the positive reviews - I really can't imagine how people can walk in them! Since I've been wearing them and its too late to return them, I'll continue to wear them around the house,and maybe to go to the beach if I'm not planning on doing a lot of walking. Other than the sole, they are comfortable and I like the way they look.  I wish I had gotten a different pair.
