AFS 8000 Mountaineering Boot

Asolo designed its Men's AFS 8000 Mountaineering Boot for technical mountaineering, boasting a low weight that belies its high level of performance. The Pebax shell keeps the boot very stiff and strong, and yet the shell-cuff-tongue structure ensures the sensitivity you need to hike and climb comfortably. Asolo wrapped the Pebax shell with a high-density Pebax Asoframe for long-lasting durability. The removable inner boot features smooth velveteen lining and Thinsulate insulation that keeps your foot warm in subzero temperatures. Both the shell and lining have separate lace closures to provide a customizable and completely snug fit.

Asolo built the Asoframe midsole with injected carbon fiber to offer stability and support without the weight; an added heel insert made of microporous rubber brings the comfort you need to stay on your feet all day. The Vibram nilgiri dual-color sole simultaneously gives you an excellent grip on all sorts of terrain and enhances your comfort with its dual-density platform. The AFS 8000 is compatible with step-in crampons.

  • Extreme weather boot built for ice scrambling 5000m peaks
  • Pebax shell maintains stiffness suitable steep terrain
  • Removable liner features Thinsulate insulation lined in velveteen

  • Familiarity: I've used it several times
  • Fit: True to size

Bought specifically for a trip to Aconcagua. These performed very well down there. Have since used winter mountaineering in Colorado.
These boots feel very sturdy and solid. They appear bulky but have a precise fit and feel agile once on your feet. The double lacing system makes them feel snug for moving on varied terrain but not too tight to cut off circulation. The cuff is a bit shorter than many other mountaineering boots, but I thought this gave a bit of comfort for stomping around on rocks and snow. Still able to scramble and climb easier technical ice decent enough. Never had any issues with blisters or hotspots. They do have a relatively roomy toe box. Overall they're warm boots. My feet only start to get cold at about -20f in these.
Mine are also quite durable. Have had them for three years and don't have any breakdowns or problems either in the plastic outer boot or the liner. With proper care and use I expect them to last a long time.
I typically wear an 8.5 or sometimes 9 in other shoes. Initially bought the 9.5 but they felt too big so returned for 9's. 9 was the perfect fit.

Good boot, could be better...

  • Familiarity: I've put it through the wringer
  • Fit: Runs small

Bought theses boots for a 6 day mountaineering seminar several years ago. Like any good brand, it's how well the boots fit. Asolos fit my feet extremely well, so I tend to gravitate toward this brand over others like LaSportiva (Scarpa also makes a good boot, but their boots fit my feet poorly).

The boots have been used for both mountaineering and technical ice climbing and have held up very well. They are warm and comfortable. The only problem I have is the velcro closure on the inner boot is starting to rip off. But the outer shell has two sets of laces to help keep things tidy.

This boot ran a touch smaller than normal. Had to get a half size larger U.S. than all the other footwear I have, including from Asolo. They aren't as articulative for technical ice climbing as a good leather mountain boot (like the Eiger GV, or my old Annapurnas which I still use), but they work well enough for confident foot placement.

For mountaineering, or spending more than a single night in snowy alpine terrain in sub-freezing temperature, theses are pretty fantastic. I wish they were lighter (they ARE heavy), and wish the velcro closure on the inner boot was constructed better, but I can't complain about the comfort, fit, and warmth of the boot. They handle snow, rock, ice, cold temperatures... I like em.

Very disappointed in the quality

  • Familiarity: I've used it once or twice and have initial impressions

I brought these for winter climbing trips when i need extra warm feet but on there first trip they basically started to fall apart. first the liner booties sole started peeling of and the seam seal tape also all peeled of the liner boot. Then the outer shells tongue started to split across where it bends from normal movement. I was very disappointed in how these boots feel apart so quickly in so many areas of the boots. no more double plastic for me, Spantik here I come.
