Meet my new role model: Roller-derby superstar Michelle Steilen, a.k.a. Estrojen. Why? Well, just watch this video. Created as a commercial for skate company Bones Bearings, Steilen adds a “woman’s touch” to some of L.A.’s sacred skateboard spots. In other words, she grinds, shreds, and falls (big-time). And yes, we’re woman enough to profess awe at how hard she wipes out in those shorty-shorts.
