What a genius combo. The plush Australian sheepskin boot gets a kick of heavy metal. The studded suede Koolaburra Taylor Boot ($350 at Koolaburra) with a buckled moto strap is our new obsession. In three words: full-on rock star. These badgirl boots add instant attitude to basics or a tough edge to balance soft, feminine looks. Plus, the practical rubber sole has enough traction to get you through major drifts.
