Bates-never unless you like your socks rolled in your boot/ too little footbed to stabilize on side hills
Danners-almost any
Meindls-almost any
Asolo-almost any
Agree wwith BK, this is torture country. Buy the best you can afford, break them in properly, get really good socks-change them often during the day. I have two pair of uninsulated Danners and one pair of Pronghorns (Danner) that have worked for me for the past few years. We issued Danners.
Find a really tall hotel in your area and run the back stairs, first in your boots, then in boots and pack until you puke-daily. I live at 5000 feet and find it sooo easy to run when I go to San diego-coming back it's tough to get back in it. Altitude will get you, the dry air-less that 20% humidity- will get you. Idaho at 9000 feet could make you very sick!
I ran the USMC Mountain Warfare Training Center near Bridgeport, Ca. we tortured flatlanders for the first week they arrived. we also tested boots, bags, tents, goretex-types, socks, climbing and skiing gear. We also condcuted search and rescue ops. Often we'd find lost folks suffering from altitude sickness and dehydration. Prepare for those wicked possibilities. JMO
