===Alpine touring===
[[File:Tourenschuhe01 kl.jpg|thumb|Modern alpine touring boots from different brands. Often the inner boot can be worn separately, as shown with the red exemplar. Also common is a lever as seen on the back of both boots to switch from a rigid "ski" position to a flexible "walk" adjustment.]]

Although randonnée is considered as an alpine sport, it basically combines the cross-country stride for uphill portions and then conventional alpine techniques on the downhill. The equipment uses most closely compares to modern telemark systems, with a stiff plastic boot offering good downhill control, and a binding system that allows it to pivot at the toe for cross-country striding.<ref>Ronald Eng, [https://books.google.com/books?id=QupdBAEgpGEC&pg=PA329 "Mountaineering: Freedom of the Hills"], The Mountaineers Books, 2010, p. 329</ref> Different models trade off light weight against downhill performance. They have a rockered, rubber sole to allow for easier walking. This means that they will not fit in ordinary alpine bindings. Instead, the interface between alpine touring boots and bindings is defined by [http://www.iso.org/iso/pressrelease.htm?refid=Ref1194 ISO 9523]. Other attachment methods exist and prominent amongst these are the ''Tech'' bindings and fittings that were first commercialized by Dynafit as the TLT. As yet, these are not covered by an international standard.
