I happen to be an expert of sporthills...
First off they are the finest pants ever made, by a man who went to the finest High School ever created (Oakton, shameles plug).
2nd, people can't tell the difference between the relaxed tight fit of sport hills and the really tight fit of spandex. Its really quite a shame.
3rd, both of my pairs have stirrups, because they ones with stirrups were on sale, and I'm cheap.
4th, I constantly get shit about having tight pants with stirrups, especially when I wear them to class because I don't always change out of my running clothes. A girl once told me that only girls wear pants with stirrups. I ran away, because its against my beliefs to engage in converstation with girls.
5th and finally I wear them anyway, and you should too, because they are the best damn pants ever created.
