I used these about twice a year when I went to the Alps. I've used them a total of 7-8 times. The soles are still in good condition. The exterior has some scratches from use, but it's still in pretty good shape. I think they can still be used extensively. Are you someone who usually uses trail running shoes for low mountains, but doesn't want to buy expensive new ones just for the Northern and Southern Alps or Yatsugatake?
