Sure-footedness refers to the ability, especially when hiking or mountain climbing, to negotiate difficult or rough terrain safely. Such situations place demands on a person's coordination and reserves of strength as well as requiring sufficient appreciation of the terrain. A person who is sure-footed is thus unlikely to slip or stumble.〔Soanes, Catherine and Stevenson, Angus (ed.) (2005). ''Oxford Dictionary of English'', 2nd Ed., revised, Oxford University Press, Oxford, New York, p. 1775. ISBN 978-0-19-861057-1.〕 On many hiking trails and mountain tours, sure-footedness is assumed to be a pre-requisite without ever being defined. The term is frequently used in the literature presumably to ensure that the reader is made sufficiently aware that, under certain circumstances, one false step may lead to serious consequences.〔 == Required attributes == Although there is no standard definition of sure-footedness,〔(''Was ist Trittsicherheit?" ) by Csaba Szepfalusi, Edelweiss Zeitung, Issue 4, 2003, pp 6-7 at www.oeav-events.at. Retrieved 1 Jun 2014.〕 the following is a list of attributes that, as a rule, constitute what is generally meant: * Possession of sufficient coordination to progress over uneven ground as intended, without losing one's balance. That also includes being able to compensate for small slips when moving forward, without any serious consequences. * Correct assessment of the ground, both in terms of usable footholds or steps and also the level of grip they afford. One must be able to do this on all types of terrain, including scree, rock, ''schrofen'', bare earth or firn, and also in wet conditions.〔 * An ability to recognise those parts of the route which need to be negotiated with particular care due to the risk of falling. * Proper assessment of one's own level of coordination and ability, even when tired, in order to adjust one's rate of progress accordingly. Experience has shown that sure-footedness decreases in the afternoon due to physical and mental fatigue. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Sure-footedness」の詳細全文を読む スポンサード リンク
