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.

Borrowed them from a climbing buddy who'd purchased these B3 mountain boots for planned late Autumn/Fall expeditions to Alaska, Northwest Canada, and Chamonix. So haven't yet been tried out in the frigid conditions they were intended 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 felt 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 the typical British or Western European climate of the late Spring and Summer months.

Tried a lot of the best Italian and USA companies. These blow them away dollar for feature. Mammut hits a home run with these.


  • All the well thought out included features...


  • All the boots I tried previously...

Outta the box comfortable immediately...!

I'm probably incredibly stoked because I got an amazing deal on these. This is one of those times when it wasn't too good to be true—deal vs product-wise.

Most notably, heel locking lace system with lace locking lower eyelets. Very lightweight comparably. Semi-auto crampon compatible with top of the line Vibram soles that make a fantastic backpacking long distance boot also. Waterproof uppers with nice scree evading neoprene gaiter, carbon fiber insulated last makes it light as heck. Lastly, the color scheme has no neon colors...😒 phew...

These feel like my old Frye boots from the '70s comfort-wise.

Time will tell regarding durability, but my experience with Mammut's clothing is top notch. Let's hope Raichle made them a good long lasting boot.


Hiking four seasons in the Northeast since the '70s.
