I worked wild land for five seasons. I learned to take care of my feet. I wear la sportiva glacier evos. They are the best boots for me. They have awesome ankle support. A little warm in summer months but not too hot. They do not have a huge heel which I love because it is more of a natural walking postion. We are not made to wear heals. They also have a big toe box which takes some getting used to but is also more natural. They are fairly popular in the wildland setting for good reasons. I lost count on how many pairs I have bought. Scarpa is also a popular boot there also. Oh as far as break in time, I bought a new pair half way through season and spent the next 2 weeks working 16 hour days on a hotshot crew in Idaho national forest. No blisters. I wear these boots religiously out in the field, it doesn't matter what I'm doing.
