I reckon you're right, I would be better served by a trail runner. Thank you for figuring that out for me! There seems to be a lot of variation in drop height and cushioning in this category... I'll have to do my research to figure out what I need, though my guess would be a higher drop and more cushioning since that's what I'm used to. Is the Bushido II your go-to trail running shoe or have you tried Scarpa or Salomon shoes as well? I'm all ears for any recommendations you may have.
You know what, I just might get in touch re: Chile. My plans earlier this year fell through because of coronavirus but hopefully can find time to hike the W or O in December!
Thanks so, so much for all your help!
