We really love the Zero G series as backcountry tweener boots that combine the best of both worlds with focus on weight/mobility and performance.
"The power of lightness. To date, ski touring has involved compromising downhill performance to save on weight. Those days are now over. The Zero G Tour Scout W weighs just 1,360 grams and boasts a 55° range of motion in hike mode. A 4-buckle design with a flex of 115 makes the Zero G Tour Scout W second to none in downhill performance. So, feel free to go farther, higher, bigger, and faster. Live the Moment with the Tour Scout W."
