I found my old climbing shoes damaged after I returned from Mt. Ege-san. I'd used it about 15 years. I changed the sole twice.
It can't prevent water coming inside now. Some cracks were there on the surface. I should to decide the end of it.
I'd climbed many mountains with the shoes, such as Mt. yarigadake, hodaka, kumono-taira, tsurugi, Ystsu, and Miyanoura, etc.
