Thank you for viewing. This is Expert of Japan's chromoly 10-point crampons. They were only used once for a shoe fitting for training purposes and have not been used for mountain climbing. I would be happy if someone could use them as I am organizing my equipment. Made of the highest quality chromoly steel. These are top-of-the-line products with heat treatment and electrodeposition coating. They feature a heel binding wire system for easy and quick attachment and detachment of the crampons. They come with snow plates to prevent snow from sticking to the soles of your shoes. The special design allows the crampons to be attached to the center line of the left and right shoe soles. By adjusting the joint length, they can be used with not only trekking boots but also various mountaineering boots, including snowboard boots. Comes with a dedicated case. Reference retail price: ¥21,000 ≪Size≫ Overall length: 325mm - 215mm Weight: 660g *Catalog size ⭕️ Adjustment wrench included. ⚠️ One of the left snow plate claws is shorter (photo 4). ⚠️ Please refrain from purchasing if you are concerned about minor details.
