rmsgear(sponsor) carries mountain boots now, for the life of me I can't remember the brand now and I don't think they are on the website but you can call and ask, they have an 800 number. The biggest key is knowing your foot profile, wide, narrow, normal etc! Different brands and even models in the same brand sometimes run different widths. I thought I had normal width feet, turns out they are narrow and getting boots that fit properly was probably the biggest game changer for me elk hunting. I feel I was 50% less fatigued at the end of the day with boots that were more than just the right length, but actually right length and width too!
