Near perfect balance between comfort and fit, durability, features and innovation, grip, insulation, support, sure-footedness, and weight
- Patented Base-fit 2.1 system utilising free sliding doubled heel strap cords to improve heel support, minimise heel lift, and prevent blistering
- Hard-wearing 3.0-2.4mm full-grain Idro-Perwanger leather
- Gore-Tex Duratherm Insulated Comfort Footwear (PA/PES) membrane provides sufficient insulation down to c-25°C(EN ISO 20334)
- Integrated Neoprene half-gaiter
- Resolable Vibram Maton sole
- Double insulated Carbon innersole offers improved insulation and increased rigidity for minimal weight
- Bonded high and thick rubber rand
- Individually adjustable 3-zone lacing system with locking D-ring.
- 3-D feet lining and mapping for optimal heel and arch support to improve insulation and prevent pressure points
- Memory foam molds to individual foot for effective cushioning of instep, shin, and ankle
- Feel reasonably comfortable to walk in on near level or easy gradients for such a rigid (B3) mountain specific boot
- At 891g (UK size 8.5) surprisingly light for such a generously featured, well insulated, and rigid (B3) leather winter mountain boot
- Perhaps a bit expensive at £360-(US$475)RRP. Would have been unaffordable without offer of price match
- Toe-box on the narrow side for those (like myself) with wider feet, particularly once your feet and toes start to swell.
- May have to look eleswhere if going up a size AND wearing light-to-medium weight socks and liners isn't an option.
- Slight reservations about having the free sliding double heel strap cords(forming part of Mammut’s Base fit 2.1 system) being partially exposed and potentially susceptible to damage from crampons and ice axes etc.
Handsome looking boots.
Recently purchased these B3 mountain boots for planned late Autumn/Fall expeditions to Alaska, North West Canada, and Chamonix. So haven't yet tried them out in the frigid conditions they were bought for.
But they have seen some use when engaged in less technical (grades I-II) climbing and scrambling in Northern England and Scotland.
I was pleasantly surprised at how reasonably comfortable they feel when walking, for up to a couple of hours, over fairly level ground or gently rising gradients. Especially for such a stiffly soled (B3) mountain specific boot.
Perhaps a little warm for climbing and scrambling during typical British summers though.
