Lange boots work. In fact, they work so well that they’re the overwhelming choice of World Cup ski racers. The brand has more victories and athletes on the circuit than any other boot manufacturer. Still, what’s function without fashion? And what’s fashion without sex appeal? Always the innovator, Bob Lange understood this, and thus the Lange Girl was born. “The Lange Girls were always beautiful, and some of them could ski, although they did so barely clothed,” says Richard Allen of Vintage Ski World, an Aspen-based shop that is one of the only places in the world that you can find old Lange Girl posters. (Allen sells the posters along with a wide variety of other historic and collectible ski memorabilia). “In the early days, the Lange Girls were on the slopes skiing,” he says. “The later Lange Girls were models, and most of them did not ski.”
