The Dynafit TLT6 Performance CR Ski Boot is not for the faint of heart. This expert level touring boot is for the serious, committed, and sometimes crazy. It's not only capable of skiing gnarly terrain it kind of insists on it. Its Grilamid shell resists extreme cold and stands up to anything conditions you'll find in the wild and rugged backcountry. A carbon fiber and Pebax cuff and rear spoiler deliver security and power when bombing down steeps at frightening speed. But all this strength and capability shouldn't scare you, because this boot comes equipped with a foot loving Custom Ready liner, anatomic and moldable to your every curve and arch. Its lightweight warmth gets a boost with an aluminum sheet on the bottom to reflect heat. And this closed cell liner features a destructured flex zone for easy hiking. In walk mode, you have a 15 18 degree release angle, and the cuff rotates 60 degrees for comfortable convenience. A hassle free two buckle Ultra Lock buckle system battens down the hatches like you're going to war. But, no, you're just out for rip roaring fun.
