Cons: They lasted about as long as I expected, 2 months. Mind you, they were only used once (sometimes twice) a week for 2 months, so about 14 wears I'd say. The elastic has started to come undone and separate from the knitting. There's lots of pulls in the knitting where they got caught on something as well. They don't wash very well (and I washed them as delicates and in a lingerie bag), meaning that they just don't have the same feel after they've been washed once, and I'm guessing that probably contributed to the beginning of the material breakdown. Not sure how many more times I can wear them before the elastic will completely unravel from the top part of the legging, but I will wear them until they don't hold up anymore!

Pros: The foot part held up well, and they were extremely stretchy, which was good because I have a bit thicker thighs than most waify dancers ;) They never felt like they were too tight or constrictive, even at the thickest part of my thigh, and they were soft and comfortable during the colder months. Once summer started I would only use them for warmup and when I got too hot, remove them.

I would purchase these again, because I'd like to think that maybe I just had some bad luck with the elastic falling apart, and give them one more try before ruling them out. For the price, they aren't that bad!
