Gore-Tex Performance Comfort gives rugged waterproof protection as well as performance-oriented breathability for hoofing it up the mountain. The upper is composed of Schoeller's stretchy, breathable softshell material, and Mammut's Georganic 3D technology fits the upper precisely to the contours of your foot shape. Underfoot, the Taiss features Vibram's Ascension Litebase sole for reliable traction on various terrain, including crampon compatibility.

    Good support, Light, Narrow toe box...

    • Familiarity: I've used it several times
    • Fit: Runs small
    • Size Bought: 11.5
    • Height: 5'11"
    • Weight: 220lbs

    Just took these for a 20 mile spin with a 50lb pack. First impression was good. Very light, great support for the weight, and great build quality.
    The initial few wears around the house left me with the impression that fit was pretty true to size, but BE WARNED! What I couldn't tell until I got some miles on them was that the narrow, almost pointed toe box caused the boot to put a good deal of pressure on my smallest toes on any kind of sustained down hill. I would advise folks with average width feet to consider sizing a half size up, and those with wide feet going a whole size up or to look elsewhere.

    I'm getting a half size larger pair on the way ASAP and will update my review when I get some miles on those.

    So light, comfortable, versatile.

    • Familiarity: I've put it through the wringer
    • Fit: True to size
    • Size Bought: 9.5
    • Height: 5'10"
    • Weight: 175lbs

    These are my new favorite boot for pretty much everything that isn't cold temp, ice climbing, or pure winter mountaineering.

    The first thing you will notice when you put these boots on is the fit - they are not only comfortable, but the heel feels solid, and the toe box is roomy, but not oversized.

    The other thing i have noticed is how low profile they appear on foot. They are slim - and coupled with the weight of just 1lb, they are super agile.

    They are stiff where i want them - right under the mid sole - but have a rocker to them that makes hiking feel natural.

    They are essentially a technical hiking boot, with the stability and feel of a 3 season technical mountaineering boot. They take a semi-auto crampon beautifully and have a very burly vibram outsole for their weight class.

    If you are looking for a boot that is more than a hiker - where you will spend some time crossing snow fields, or meandering through some boulder fields - especially with a heavier pack on, these are a killer boot.
    I am a 9.5 street shoe and these were perfect right at the 9.5. so True to Size.

    I am definitely planning a cascades trip to climb a volcano now that i know what these boots are about.

    And did i mention how LIGHT they feel?
