The rubber parts of this old model are cracked in places. When I used it last year, it didn't affect its waterproof or cold-weather performance, and I was able to use it without any problems. I'm selling it because it's become difficult for me to go mountain climbing due to illness. *Following a comment, I checked the YouTube channel "BC Hotaka Mountaineering School" and their video "Frequent Sole Damage of Mountaineering Boots During Climbing!" and found that the condition of this product corresponds to the state where sole replacement should be considered. If you are considering purchasing this item, please consider resoling before making your purchase. Thank you.
