The Lange World Cup 100 mens ski boots are low volume boots that offer enough flex to ski all mountain. Like the rest of Langes World Cup boot line-up, the 100 offers a snug fit and low volume toes and heels. However, with a flex index of 100, this boot is much more forgiving than Langes true racing lineup. This is a great all-mountain boot for narrow feet or former racers who have to have a snug fit. The relaxed flex makes powder skiing, cliff dropping, and cruddy turns much more enjoyable.
