Protrude from the lower portions of the heel plate 2 and the front plate 1, so that the effect of preventing slippage on ice and snow and in mud can be sufficiently exhibited. Needless to say, since the lateral displacement prevention pins 5, 5... Stand up on the upper surfaces of the heel plate 2 and the front plate 1, the collar holding chain 6, the locking bar member 14, the side holding In combination with the action of the chains 7 and 7 and the toe portion holding chain 8, there is no possibility that the heel plate 2 and the front plate 1 will be displaced back and forth or left and right during walking. Therefore, walking safety can be further secured. In particular, since the positioning of the locking bar member 14 is ensured by the collar lifting belt 13, the forward displacement of the heel plate 2 and the front plate 1 is reliably prevented, and the collar lifting belt 13 Since the movement of the heel plate directly in the left-right direction is also suppressed, the shift in the left-right direction is prevented.

  Further, the front and rear connecting portions 9e and 9f of the elastic band 9 are drawn and engaged with a notch engaging hole 12b at the lower portion of the end portion 12 of the strap end that is disposed on the instep side ankle portion of the mountaineering shoe S. Since it is stopped and placed only on the upper side of the mountain climbing shoe S, the risk of contact with rocks in the galleries where the snow has disappeared, tree branches in shrub belts, tree roots, etc. is reduced. The risk of damage is very low. In addition, since the elastic band 9 is provided with a protective coating, there is no possibility of causing damage such as breakage even if it comes in contact with them, and the hook suspension belt No. 13 is a strong cloth material that has a low possibility of coming into contact with rocks and the like, and even if it comes in contact, there is no possibility of causing damage easily and can be used more safely.
