You want a second, lighter ski touring setup. Or you know, right off the bat, that you will prefer lighter weight ski gear. But you are on a budget. In this niche, the Atomic Backland Carbon is the best backcountry ski boot we have assessed. It uses proven technology and brings ultralight performance to a price point much further below close competitors. It is comfy and tours uphill like a dream. Pair it with similarly lightweight skis and bindings, and you will fly up entire mountains, fresh and ready for huge downhills. 
You'll pay a bit of a price on those downhills. The lower cuff and softer flex of these lightweight boots will never ski downhill like beefier options. We are confident that you will be more than willing to accept this compromise. However, you need to fully understand what you are getting into. These are suitable for expert-level skiers on small skis, that are willing to tone down the energy in their downhill skiing in exchange for uphill efficiency. Further, the fit of the Atomic Backland is relatively high volume. For optimum downhill performance in any sort of boot like this, a close fit is best. These will perform best for those with wider or higher volume feet. Making them work on narrower feet might not be worth it; check out other options if you have narrow feet.
