Yes, I love them too! They can be exceptionally warm in winter, and most times of the year they work well. They're kind of a 'fashion plague' in my city but this is one plague I welcome because I get to see sexy women's legs all over the place. There's just about nothing more attractive to me on a girl than simple black leggings. Something about them makes great legs even better. Do I sound crazy about legs?!?
Also, I like warm kittens! 😉
