Editing Ski binding (section)

=== Norheim—ca. 1850 ===
[[Sondre Norheim]] demonstrated telemark skiing before 1866, and the Open Christiania turn in 1868, both made possible with a binding design which dated back to the late 1840s. This added a loop of twisted birch roots that ran from the existing birch root toe loops around the boot heels and back. This allowed the heel to lift as before, for walking and gliding, but better held the boots to the skis allowing greater control. This enabled Norheim to control the skis with his feet and legs, replacing the former technique of dragging a large pole in the snow on one side or the other to drag the skier in that direction.<ref name=":2">{{cite journal|last=Lert|first=Wolfgang|title=A Binding Revolution|journal=Skiing Heritage Journal|date=March 2002|pages=25–26|url=https://books.google.com/books?id=wlgEAAAAMBAJ&pg=PA25|access-date=3 October 2012}}</ref> This control led to the development of the [[Telemark skiing|telemark]] and [[stem christie]] ski turns.<ref>{{cite journal|last=Lund|first=Morten|title=Norway: How It All Started|journal=Skiing Heritage Journal|date=September 2007|pages=8–13|url=https://books.google.com/books?id=SlgEAAAAMBAJ&pg=PA9|access-date=3 October 2012}}</ref>
