I can't use my skecher flip-flops to work (or the sneaker shoe either for that matter )- but, I would love too since I do a lot of walking about. LIke I stated earlier, I did feel the difference.
I've noticed that a couple of the stockers at my work wear them daily, but I haven't noticed that they've lost weight or toned. One lady quit wearing them & I asked her wy she did so. She said that they were just too painful. They are definitely not Weight Loss shoes, just toning shoes.
