I am a die-hard leggings wearer and I know these are the best there are. They are comfortable, never fall down or get baggy and they retain their dark black color. They also have a good amount of spandex, so they suck you in a little bit without being constrictive. I've been wearing them for years, and they are durable, as well. Only caveat - I wash them in the washing machine on cold, but then I hang them to dry. They will last for years and years. Highly recommended.
