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.
"A four-buckle women’s touring boot that doesn’t compromise weight for skiing performance, the Zero G Tour W is a true backcountry gem designed for intermediate to advanced female backcountry skiers. Weighing in at 1,500 grams (for a size 26.5), it boasts a 55-degree range of motion for mega mobility on the skin track. On the descent, a four-buckle design with a flex of 105 makes the Zero G Tour W a great downhill performer."
