My Mnt hunters Ktalon soles wore out in one hard year of hunting. Called em and they wouldn't help me out. So I too paid the 150$ to resole, a heavy Vibram lug. 6 months later they came unglued in the middle of a Hawaiian sheep hunt...Another call and letter with pictures to Montana, Kenetrek would not back thier product. I have since been using another brand. BH1
