    It looks like it'll go.

    Those were the words your buddy told you before you set your sights for an epic first ascent, and you can rely on the La Sportiva Men's G5 Mountaineering Boot when you're ascending unknown terrain. This highly technical big mountain boot boasts a stretchy Cordura gaiter equipped with a waterproof membrane and a heat-sealed zipper to keep wetness at bay. The durable upper features flex zones to keep you trekking and climbing anatomically, while the insulated felt works with the insulated footbed to maintain warmth. Vibram's Matterhorn rubber sole includes large lugs and step-in crampon compatibility.

    Boa system is amazing but...

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

    • Height: 5'11"
    • Weight: 166lbs

    The heel lock down for climbing and release for belaying is amazing. Huge upgrade over batura 2.0 in that regard. But like others say, if you are not dealing with frozen terrain, they leak. But I'm a roadside cragger in cold temps so they are the best ice boots I've used. Anything involving slush, stream crossing they are a no-go.

    Is it really true that this boot isn't waterproof? The company claims it's waterproof. Any more details on this? I do a lot of spring climbing in Colorado, where conditions are quite slushy. Thanks in advance.

    The best!

    I LOVE these boots. Upgraded from the Nepal Evo GTX and they are so much better imo. Very comfortable, light, warm and the climbing performance is awesome. The Boa lacing system is pretty slick too.

    The best!

    Not waterproof??

    • Familiarity: I returned this product before using it
    • Fit: True to size

    So I saw some reviews on the La Sportiva website stating that this boot is not waterproof. I got them myself to take a look, and these boots are really sweet. BUT THEY ARE NOT WATERPROOF. There is a direct path for water to enter the inside of the boot. The zipper is not waterproof, and the inner boot has no gusset or tongue (it's an open half-boot style). Thus, if you step in a puddle, saturated slush, river, or anything else, there is an clear path from cold water to your foot. I was pretty shocked by this, so I talked to the La Sportiva folks. After reviewing my comments, they are now updating the description of this boot to not waterproof but instead "highly water resistant." To be sure, if all I did was roll up to roadside crags and climb in super cold temps, these things would be a dream. But the risk of water logged feet for any alpinism seems a very high cost. How often do you cross a river, get slogged in a bog, or find yourself working through slush? I am disappointed.

    Do everything, stay warm, be agile.

    These are the last pair of mountaineering boots i will ever wear (well, until they make a new version of this) - super light, agile, extremely warm, and great for every application from ice climbing to casual ridge walking.

    They are essentially the same weight as the Phantom Tech but seem to climb a bit more natural, and fit my feet a bit better.

    An easy decision for any mountaineering, especially if you think you'll be climbing in colder temps.
