I bought a pair of the sketchers and I have to say that they're super comfy. The thing is this: I don't wear them to the gym because I can't imagine doing the certain cardio stuff with them on...I only find them suitable for walking. But, when I'm doing my errands, I don't really like to wear sneakers....I like to wear cute shoes that match my outfit.
So, I don't wear them much at all. If I did, I could comment on how they are for the toning. I bought them after I saw a woman wearing them and she told me she felt a difference. I really should wear these more, but I guess I'll have to sacrifice style for substance. I should wear them at least when I walk my dog, but most of the time, I honestly forget.
