- Who it's for
- Mountaineers tackling ice and alpine objectives who want a single boot that can double up with a liner for colder conditions. Best suited to lower-volume feet, with one host noting a half-size-up fit in La Sportiva sizing.
- What people are saying
- Hosts praise the BOA dial for on-the-fly fit adjustment between hiking and climbing, and the boot's versatility across long days in the mountains. The removable liner's fast-drying performance and the boot's light weight are called out as genuine strengths.
- Worth noting
- Lower-volume feet fit best; one host wears a 45 at street size 11.5. One note comes from a host who hasn't yet used this boot personally, so firsthand experience in the notes is limited to two of three hosts.
Joe Kalis's review
The next generation ice and alpine boot for me. I really like being able to adjust the fit of the boot using the externally accessed BOA dial, with looser fit when hiking and tighter when actively climbing!

Technically, I wear the G5 Evo boots, but you can't get them anymore. These are what I'm eyeing up next, and think they make the best upgrade from the Evos. I won't go back from BOA, and they climb and hike super well. I've done many 12+ hour days in them.

The perfect one-boot quiver for virtually any mountaineering or ice objective in the lower 48 and beyond. Warm not hot, light and svelte. The removable inner liner and insole means you can rig it as a single or double boot depending on expected temps. The liner is soft and flexible, and dries super fast in your sleeping bag during the night. Best for lower volume feet, I'm a street size 11.5 and wear a size 45 in Sportiva boots generally.
