Aside from being attractive and very comfortable, these toning sandals work extremely well. I purchased these at the beginning of last summer and wore them until last fall (unfortunately, the white started turning brown from so much wear, which is understandable). Without even working out the entire summer, I kept dropping jean sizes because of diet and, well, these sandals! My buttocks and legs had never been so firm and cellulite-free in my life. I definitely recommend these. For the newer styles, they could be a bit pricey but are well worth the $40 you'll pay for them.
