Purchased in the winter of 2025 and used once. As shown in the photos, there is some rust on the aluminum parts. Size: L/XL Retail Price: ¥13,750 (tax included) The advantages are that it's lightweight and easy to carry, and the short claws make it easy to walk. However, it's a 10-point crampon, so please be aware that it is not suitable for difficult snow mountains. I used it with my 27cm Salewa mountaineering boots, and the size was a perfect fit. The size can be adjusted at the heel, so it may be compatible with larger mountaineering boots if the toe fits. I believe it's still a current model, so please try it on with your mountaineering boots at a store. If you are interested, please consider it.
