In 1952, skiing pioneer and innovator Hannes Marker founded the Marker ski binding company and introduced the first commercially successful releasable ski binding. What followed over the years were many changes, evolutions and market firsts; such as the Simplex Toe; Rotomat Heel; Active AFD; Stainless steel AFD; Mechanically Operating Toe Cups; Twincam; Full Spectrum; Biometric; and revolutionary performance interface systems like Selective Control and new Piston Control.
