Hi Chels --
They are very comfy, and seem to really be bottom/leg toning.
My younger sister, who is an exercise/aviation pysiologist, recommended them. She and the older sister, who is a nurse practioner, both wear them when they go walking. If the younger sister wasn't in the U.S. Air Force and has to wear an uniform to work -- I think she might wear them all day long.
I also have slippers (I do not wear shoes in the house) that are supposed to be toning. And, I have order some "Fit Flops".
I have beige Shapers that look like Mary Jane shoes (I gave the too big black trainer ones to DH and he likes them). And, I have seen the same Mary Jane style in black -- so, I may (eventually) get those -- and then I'll try to wear them when I go out and about running errand, etc. They look less like trainers.
