Brace yourself, this is going to get honest. These things are awesome, first off, and I'm glad I bought them. They felt good; comfortable and sexy they didn't swish when I walked. No lines from shorts or spanx. Plus, I could pee without having to adjust them. (If you're a big girl, you know this is an issue with tights, shorts and every other method of thigh management we employ.) They work great for everyday or a night out on the town. I, though, wore them on an overtime shift at my high-performance job. They held up amazing... for nine solid hours. It was at hour ten that they started to get uncomfortable. Once I started trying to adjust them, they rebelled, rolled and I had to remove them. Don't get me wrong, they're amazing. Buy them, seriously, and use them as intended. Just do not expect to bust out a long, hard, high-stress physically active day in them. Actually, they would have done just fine in a day like that if it wasn't overtime.
