These are 6-point crampons. They ensure safety on slippery, snowy paths. Size: Free size, 21.5 - 30.0cm Can be attached to any shoe. The straps were stained, so they have been replaced with new ones and used only once. They have not been cut to length. I purchased them a few years ago at a mont-bell shop for approximately 5300 yen (including tax) and used them several times. Due to the nature of the product, there is some wear and tear, but I think they are still perfectly usable. Please consider this item with the understanding that it is a used item. To reduce shipping costs, I plan to remove the crampons from the box and fold the box to include it. Please let me know if you do not need the box. - Brand: mont-bell - Model Name: Snow Spike 6 - Type: 6-point - Size: Free size - Included: Straps, storage bag - Box and instruction manual included - Materials: Rubber, metal *Please read the profile before purchasing.
