Using sex appeal to sell products isn’t new. And it wasn’t a revolutionary idea in 1962, either. But Lange was the first ski boot manufacturer to truly tap into the bourgeoning sexual revolution of the 60s and his posters found an enthusiastic reception in the freewheeling, hard partying ski culture of that era. Like his technical innovation with plastic boots, the Lange Girl concept would be copied over the years by the competition: Most recently, Nordica introduced its own harem of “Nordica Girls.” And the defunct Hanson boot company used to rely on sexy models to help sell its brand. Even ski companies have jumped into the fray. The North American distributor of Stockli skis ran a bizarre ad for several years featuring a strange reliance on a blonde model posing with the company’s product, an ad that had nothing to do with skiing. A marketing and creative disaster, it’s probably one reason that the company’s skis remain virtually unknown here.
