Purchased 3 years ago and used for hiking about 5 times. I've hiked from low mountains to Hakuba and Oku-Hotaka, so there's a certain amount of wear and tear, but the soles still have plenty of life left and I think they can still be used. The insoles are unused as I used others. I always maintained them after hiking. EU41 is said to be about 26.1cm in Japanese size, but I think it's a bit small.
